Comparison of gastric emptying time between breast-fed and formula milk-fed infants less than 6 months old, using gastric ultrasound-An observational study.

BACKGROUND: Fasting before elective anesthesia care is a standardized practice worldwide. The aim is to decrease the risk of aspiration leading to pulmonary complications such as aspiration pneumonitis during anesthesia care. There are different guidelines for elective preoperative fasting in children. However, there is insufficient literature measuring gastric emptying time after breast milk or formula milk feeding in infants. OBJECTIVE: This study used gastric ultrasound to determine the gastric emptying time for breast milk and formula milk in children below 6 months of age. We also compared the calculated gastric volumes among breast-fed and formula milk-fed based on Schmitz's and Spencer's formula. MATERIALS AND METHODS: This prospective observational study was conducted at a tertiary care center in India between November (2017-2019). A total of 52 infants less than 6 months of age were recruited. The study population was divided into two groups (breast-fed and formula milk-fed) of 26 patients each. Ultrasound was used to measure the antral cross-sectional area of the stomach and to calculate the gastric volume using the two classical formulas (Schmitz and Spencer's). Gastric emptying was reported when the bull's eye appearance of the gastric antrum was seen or when the antral cross-sectional area was less than 3.07 cm2. RESULTS: The number of breast-fed children whose antral cross-sectional was greater than 3.07 cm2 (cut-off value for aspiration risk) beyond 1 h was 14/26 (53.84%) while none (0) children went beyond 3 h. The number of formula-fed children whose antral cross-sectional was greater than 3.07 cm2 beyond 1 h was 17/26 (65.38%) while one child (3.84%) went beyond 3 h. Using Schmitz's formula, mean (SD) gastric emptying times were 0.35 ± 0.68 h (95% CI 0.35 ± 0.185, range 0.165-0.535) for breast-fed patients and 0.35 ± 0.69 h (95% CI 0.35 ± 0.188, range 0.162-0.538) for formula-fed patients, and were thus neither clinically nor statistically different (p = .73) Using Spencer's formula, the mean gastric emptying times were 0.12 ± 0.33 h (95% CI 0.12 ± 0.09, range 0.03-0.21) for breast-fed patients and 0.04 ± 0.20 h (95% CI 0.04 ± 0.05, range -0.01 to 0.09) for formula-fed patients, and were also neither clinically nor statistically different p = .13. CONCLUSION: In our series, the gastric emptying times in breast-fed and formula-fed infants less than 6 months old were similar. Our results support the fasting guidelines of the European Society of Anaesthesiology and Intensive Care 2022, that is, 3 h for breastfeeding and 4 h for formula milk feeding. In addition, this shows that the Schmitz's and Spencer's formulae used to calculate the gastric volume based on ultrasound measurement of the antral cross-sectional area are not comparable in infants less than 6 months.

Comparative evaluation of the analgesic efficacy of ultrasound-guided erector spinae plane block versus intrathecal morphine in patients undergoing percutaneous nephrolithotomy surgery: A prospective randomized pilot study.

OBJECTIVES: Existing research on erector spinae plane block and intrathecal morphine in patients undergoing percutaneous nephrolithotomy surgery is limited. METHODS: In this prospective, randomized study, 60 patients aged between 18 and 60 years were randomized into two groups (erector spinae plane block and intrathecal morphine). In the erector spinae plane block group, ultrasound-guided erector spinae plane block was performed, following which a mixture of 20 mL of 0.375% ropivacaine and 0.5 mcg/kg of clonidine was injected. In the intrathecal morphine group, 150 mcg preservative-free morphine with 2 mL of normal saline was administered intrathecally. The primary outcome was to evaluate the perioperative opioid consumption in the first 24 h. The secondary outcomes were to evaluate hemodynamic response to surgical stimulus, visual analogue scale score, time to first analgesic requirement, postoperative nausea and vomiting, postoperative opioid consumption, urethral irritation, and incidence of drug-related adverse effects. RESULTS: Total perioperative opioid consumption in the erector spinae plane block group was 355.0 (265.0, 485.0) µg and 240.0 (145.0, 370.0) µg in the intrathecal morphine group (P = 0.09). However, the patients in the erector spinae plane block group had significantly greater postoperative fentanyl consumption (235.0 [120.0, 345.0] µg) compared with those in the intrathecal morphine group (105.0 [30.0, 225.0] µg). There were no statistically significant differences noted for intraoperative opioid consumption, postoperative visual analogue scale score, time to first analgesic request, postoperative nausea and vomiting, and catheter irritation between the two groups. CONCLUSIONS: Although no statistically significant difference in intraoperative opioid consumption was seen between the erector spinae plane block and intrathecal morphine groups, postoperative opioid consumption was significantly higher in the erector spinae plane block group than in the intrathecal morphine group in patients undergoing percutaneous nephrolithotomy surgery.

Air-Q ILA as a conduit for orotracheal intubation in children: A randomized control trial for comparison between supine and lateral patient positions.

Background and Aims: Airway management in children is always challenging and becomes a concern if required in the lateral position. We evaluated the efficacy of orotracheal intubation using the Air-Q intubating laryngeal Airway (Air-Q ILA) in supine and lateral positions in children. Material and Methods: This study included 100 children weighing 7-30 kg, scheduled for elective surgeries under general anesthesia. They were randomized into the supine (S) group or lateral (L) group. After anesthesia induction, the child was placed in a standard sniffing position for conventional laryngoscopy in the S group, and the child was turned into the lateral position in the L group. Both Air-Q ILA and endotracheal tube were placed blindly in the supine position in the S group and lateral position in group L. The grading of glottic view, success rate, insertion time of the Air-Q ILA, and endotracheal intubation were noted in both the groups. Results: The Air-Q ILA was successfully placed at the first attempt in 47 children in group S and 48 in group L. The overall blind orotracheal intubations, including first and second attempts, were successful in 45 children in the S group and 47 in the L group (P = 0.715). Eighty percent of patients in group L and 70% in group S had glottis grade 1 or 2 compared to grade 3, 4,5 (P = 0.249). The mean time of Air-Q ILA placement in groups S and L was 15.73 ± 5.64 s and 14.42 ± 4.16 s (P = 0.195). The mean duration of blind endotracheal intubation through the Air-Q ILA was 24.88 ± 14.75 s in group S and 17.57 ± 5.35 s in group L (P = 0.002). In both the groups, none of the children had bronchospasm, laryngospasm, desaturation, or aspiration. The airway trauma evident by blood staining on the Air-Q ILA on removal was revealed in 2 cases in group S, and 3 cases in group L. None of the children in group S and 4 children in group L had postoperative stridor. Postoperative hoarseness was reported in 3 children in group S and none in group L within 24 hours. Conclusion: The Air-Q ILA can be used as a conduit for blind orotracheal intubation in children in both supine and lateral positions while maintaining an effective airway seal.

Cadaveric Study of Topographic Anatomy of Temporal and Marginal Mandibular Branches of the Facial Nerve in Relation to Temporomandibular Joint Surgery.

PURPOSE: Detailed anatomy of the facial nerve, including the variations among different ethnic groups, is essential to prevent an iatrogenic injury. The purpose of the study was to document topographic anatomy of temporal and marginal mandibular (MM) branches of the facial nerve in relation to temporomandibular joint (TMJ) surgery. The specific aim was to demonstrate detailed course of temporal and MM nerves, their surgical implications, and to compare the results obtained with the previous studies. METHODS: The investigators implemented a prospective cadaveric study. A dissection was carried out on 52 facial halves. The facial nerve was dissected according to the instructions described in the Cunningham's dissection manual. Anatomic landmarks were selected as determined by Al-Kayat and Bramley, and results obtained were compared with previous published articles. RESULTS: The study sample was composed of 52 facial halves (males, n = 35; females, n = 17). The number of branches of temporal nerve varied in dissected facial halves from 3 (n = 37 [70%]), 2 (n = 14 [26%]), to 1 (n = 1 [2%]). The distance between the lowest concavity of the bony external auditory meatus to the point at which the facial nerve bifurcates (distance B) was considerably less in the study population (1.79 cm) when compared with the reported literature (2.3 cm). There was no significant influence of gender and cephalic index on distances measured. There was 1 branch in 15% of the dissected facial halves (1 in 52) and 2 branches in 85% (44 of 52). The MM nerve was seen coursing below the inferior border of the mandible, and in 44 (85%), the nerve was present above the inferior border of mandible all along the course. CONCLUSIONS: The topographic anatomy of the temporal and MM nerves is the same as reported in the literature. The only considerable difference was found in distance B; hence, surgical procedures involving the distance B require special consideration.

Evaluation of Success of Transport Disc Distraction Osteogenesis and Costochondral Graft for Ramus Condyle Unit Reconstruction in Pediatric Temporomandibular Joint Ankylosis.

PURPOSE: The costochondral graft (CCG) is considered the reference standard for pediatric temporomandibular joint reconstruction. It has the disadvantages of unpredictable growth, donor site morbidity, and the need for intermaxillary fixation. It has been reported that transport disk distraction osteogenesis (TDDO) can result in the formation of a neocondyle and disc. We performed a randomized trial to measure and compare clinically relevant outcomes of ramus-condyle unit (RCU) reconstruction using CCG and TDDO for pediatric temporomandibular joint ankylosis (TMJA). MATERIALS AND METHODS: In the present randomized controlled trial (block randomization with a variable block size), pediatric patients with unilateral, nonrecurrent TMJA aged 3 to 16 years who had presented to our unit from December 2015 to June 2017 were enrolled. Instead of temporalis myofascial flap interposition, a buccal fat pad was used to fill the gap created by osteoarthrectomy. The primary outcome parameter was mouth opening. A mouth opening of at least 25 mm at the median follow-up point was considered success. The secondary outcome parameters were occlusion, laterotrusion, protrusion, reankylosis, neocondyle, chin deviation, facial asymmetry, midline shift, and neo-disc formation. Data were analyzed using the independent t test and rank sum test. RESULTS: A total of 24 patients were enrolled in the CCG and TDDO groups (n = 12 in each group). Trauma (40.9%) was the most common etiology with a slight male preponderance (59.09%). The mean age was 10.32 ± 2.85 years. The average distraction achieved in the TDDO group was 10.42 mm. The median follow-up duration was 31.5 months (range, 24 to 39 months). The mean preoperative maximal incisal opening had improved from 8.5 ± 4.1 and 9.5 ± 7.1 mm in the CCG and TDDO groups preoperatively to 35.7 ± 2.7 and 34.4 ± 8.9 mm, respectively, at the median follow-up point (P < .005). RCU reconstruction with both modalities resulted in improvement in all the parameters; however, the intergroup comparison showed statistically non-significant differences. No reankylosis or open bite was found. The 3-hour delayed gadolinium-enhanced magnetic resonance imaging scan showed successful neo-disc formation. CONCLUSIONS: Similar success can be achieved in RCU reconstruction using either CCG or TDDO for pediatric TMJA. Both techniques have some advantages and disadvantages. RCU reconstruction using CCG or TDDO results in formation of a neocondyle, maintenance of occlusion, and correction of facial asymmetry.

Comparison of the C-MAC video laryngoscope size 2 Macintosh blade with size 2 C-MAC D-Blade for laryngoscopy and endotracheal intubation in children with simulated cervical spine injury: A prospective randomized crossover study.

BACKGROUND AND AIMS: CMAC video laryngoscope size 2 D-Blade has been recently introduced for management of pediatric difficult airway. Our primary outcome was to compare glottic view, intubation time, and ease of intubation with the size 2 Macintosh versus D-Blade of C-MAC video laryngoscope in simulated cervical injury in children. MATERIAL AND METHODS: This randomized crossover study was conducted in a tertiary care hospital of Northern India. Forty children of 4-14 years of age were enrolled in this study. After induction of anesthesia, video laryngoscopy was performed either with size 2 CMAC Macintosh (group M) or D-Blade (group D) with manual in-line stabilization. After removal of the first blade, second video laryngoscopy was performed with the alternative blade. Endotracheal intubation was done with the second laryngoscopy. Best glottic view, time for best glottic view, and difficulty in blade insertion were recorded during both the video laryngoscopies. During second video laryngoscopy, difficulty of tube insertion and time for intubation were noted. RESULTS: The glottic view grade was significantly better in group D compared with the group M (P = 0.0002). Insertion of D-Blade was more difficult than Macintosh blade (P = 0.0007). There was no statistical difference in terms of time for best glottic view in group M and group D (13.40 ± 4.90 vs 13.62 ± 5.60 s) and endotracheal tube insertion time (24.80 ± 7.90 vs 27.90 ± 10.90 s), respectively. Number of intubation attempts was similar in both the groups. CONCLUSIONS: Size 2 D-Blade of C-MAC video laryngoscope provided a better glottic view in children with simulated cervical spine injury as compared with CMAC Macintosh blade. Success of intubation, intubation time, and ease of intubation were comparable with both the blades.

Evaluation of optimum time for intravenous cannulation after sevoflurane induction of anesthesia in different pediatric age groups.

BACKGROUND AND AIMS: The ideal time for intravenous (IV) cannulation following inhalational induction in children is debatable. The effect of age on this time has not been studied. We evaluated the optimum time for IV cannulation after sevoflurane induction of anesthesia in different pediatric age groups. MATERIAL AND METHODS: A prospective interventional study based on Dixon's sequential up and down method was conducted in children of age 1-10 years. They were grouped according to their age - Group 1: 1-3 years, Group 2: >3-7 years, and Group 3: >7-10 years. Anesthesia was induced with 8% sevoflurane in 5 L of 100% oxygen. IV cannulation was attempted at 3.5 min in the first child in each group. The time for cannulation in the next child was stepped up or down by 30 s depending on positive or negative response, respectively, in the previous child. Children were recruited till a minimum of six pairs of failure-success sequence which was obtained in each group. The mean of midpoints of the failure-success sequence was calculated to obtain the time for cannulation in 50% of the children in each group. RESULTS: Total number of children in Groups 1, 2, and 3 were 24, 23, and 24, respectively. The mean (95% confidence level) time for IV cannulation after sevoflurane induction in Groups 1, 2, and 3 was 53.6 (40.0-67.1), 105 (62.6-147.4), and 143.6 (108.8-178.4) s, respectively. This time was significantly shorter in Group 1 compared to those in Groups 2 and 3. CONCLUSION: The optimum time for IV cannulation in 50% of the children after sevoflurane induction of anesthesia was shorter in children of age 1-3 years than in older children.

Case control study: magnetic resonance spectroscopy of brain in HIV infected patients.

BACKGROUND: In vivo proton magnetic resonance spectroscopy ((1)H-MRS) studies on brain in HIV infected patients have shown significant alteration in neuro-biochemicals. METHODS: In this study, we measured the neuro-biochemical metabolites from the left frontal white matter (FWM) and left basal ganglia (BG) caudate head nucleus in 71 subjects that include 30 healthy controls, 20 asymptomatic HIV and 21 HIV patients with CNS lesion. Proton MR spectra were acquired at 3 T MRI system and the concentration (institutional units) of tNAA (N-acetylaspartate, NAA + N-acetylaspartylglutamate, NAAG), tCr (Creatine, Cr + phosphocreatine, PCr), choline containing compounds (tCho), glutamate + glutamine (Glx) and lipid and macromolecules at 0.9 ppm were determined using LC Model. RESULTS: In BG, the concentration of tNAA (6.71 ± 0.64) was decreased and in FWM, the concentration of Glx (20.4 ± 7.8), tCr (9.14 ± 3.04) and lipid and macromolecules at 0.9 ppm (8.69 ± 2.96) were increased in HIV patients with CNS lesion. In healthy controls, the concentration of tNAA in BG was 7.31 ± 0.47 and concentration of Glx, tCr and lipid and macromolecules in FWM were 15.0 ± 6.06, 6.95 ± 2.56, 5.59 ± 1.56, respectively. CONCLUSION: Reduced tNAA in BG suggests neuronal loss in HIV patients with CNS lesion while increased Glx in FWM may suggest excito-toxicity. In addition, increased levels of tCr in FWM of HIV patients were observed. The study indicates region specific metabolic changes in tNAA, tCr and Glx in brain of HIV infected patients.

Intermittent Directly Observed Therapy for Abdominal Tuberculosis: A Multicenter Randomized Controlled Trial Comparing 6 Months Versus 9 Months of Therapy.

BACKGROUND: The duration of treatment of gastrointestinal tuberculosis continues to be a matter of debate. The World Health Organization advocates intermittent directly observed short-course therapy (DOTs), but there is a lack of data of its efficacy in abdominal tuberculosis. We therefore conducted a multicenter randomized controlled trial to compare 6 months and 9 months of antituberculosis therapy using DOTs. METHODS: One hundred ninety-seven patients with abdominal tuberculosis (gastrointestinal, 154; peritoneal, 40; mixed, 3) were randomized to receive 6 months (n = 104) or 9 months (n = 93) of antituberculosis therapy using intermittent directly observed therapy. Patients were followed up 1 year after completion of treatment to assess recurrence. Patients were evaluated for primary endpoint (complete clinical response, partial response, and no response) and secondary endpoint (recurrence of the disease at the end of 1 year of follow-up). RESULTS: Baseline characteristics were similar between the 2 randomized groups. There was no difference between the 6-month group and 9-month group in the complete clinical response rate on per-protocol analysis (91.5% vs 90.8%; P = .88) or intent-to-treat analysis (75% vs 75.8%; P = .89). Only 1 patient in the 9-month group and no patients in the 6-month group had recurrence of disease. Side effects occurred in 21 (21.3%) and 16 (18.2%) patients in the 6-month and 9-month groups, respectively. CONCLUSIONS: There was no difference in efficacy of antituberculosis therapy delivered for either 6 months or 9 months in either gastrointestinal or peritoneal tuberculosis, confirming the efficacy of intermittent directly observed therapy. CLINICAL TRIALS REGISTRATION: NCT01124929.

Comparison of interferon gamma release assay & tuberculin skin tests for diagnosis of latent tuberculosis in patients on maintenance haemodialysis.

BACKGROUND & OBJECTIVES: Tuberculosis (TB) is a common infection in patients on haemodialysis. There is a definite role of treatment of latent TB (LTB) in these patients. However, diagnosis of LTB in these patients by tuberculin skin test (TST) is unreliable. There is suggestion that interferon gamma release assay (IGRA) will be more reliable test for diagnosis of LTB in this setting. Thus, we evaluated value of IGRA and TST for the diagnosis of LTB in patients on dialysis in an Indian setting. METHODS: Patients with end stage kidney disease on dialysis were included. Patients with active TB were excluded. Each patient was subjected to TST (induration of ≥10 mm was taken as positive) and QuantiFERON TB Gold In-Tube test (QFT-GIT) for diagnosis of LTB. RESULTS: A total of 185 patients were included; 129 (69.7%) were males and mean age was 36.7 ± 12.3 yr. Past history of TB was present in 18 (9.7%) patients. One hundred and thirty four (72.4%) patients had scar of BCG vaccination. QFT-GIT test was positive in 66 (36%), TST in 32 (17%) and both in 13 (7%) patients. Of the 66 patients positive with QFT-GIT, only 13 (19.6%) were positive for TST. Of the 32 patients positive with TST, only 13 (40.6%) were positive with QFT-GIT; 100 (54%) patients were negative for both the tests. Overall, 85 (45.9%) patients were positive for either of the two tests. Poor agreement was shown between the two methods. On logistic regression analysis, odds of QFT-GIT to be positive in patients with BCG vaccination was 1.23 and with history of TB 0.99, both being insignificant. odds of tuberculin skin test to be positive in patients with BCG vaccination was 1.04 and with history of TB 0.99, both again being insignificant. INTERPRETATION & CONCLUSIONS: Our findings showed that more number of patients (36%) on haemodialysis were positive for QuantiFERON Gold In-Tube test as compared to TST (17%). There was poor agreement between the two tests. No significant effect of BCG vaccination and history of TB in past was observed on both tests.

Evaluation of glottic view through Air-Q Intubating Laryngeal Airway in the supine and lateral position and assessing it as a conduit for blind endotracheal intubation in children in the supine position.

INTRODUCTION: We assessed the feasibility of blind orotracheal intubation in children using the Air-QILA as a conduit in supine position and the glottic view grading by fiberoptic bronchoscope (FOB) through it both in supine and lateral positions. METHODS: After ethical approval and consent, 60 children were enrolled in the study. In the operating room, after attaching standard monitors to all children, anesthesia was induced with sevoflurane (2-8%) in oxygen (100%). Once the children became sedated, an i.v. access was established and injection glycopyrrolate (10 µg · kg(-1)), fentanyl (2 µg · kg(-1)), and atracurium (0.5 mg · kg(-1)) were administered. After 3 min, the Air-QILA was placed in supine position and glottic view was assessed by using FOB, in supine and right lateral decubitus position. In all children, gradings of glottic view in two different positions were noted. After that all children were turned supine, and orotracheal intubation was done blindly through the Air-QILA. The success rate, insertion time of the Air-QILA, and endotracheal intubation were noted. RESULTS: The Air-QILA placement was successful in 57 children in first attempt and three children required second attempt. However, blind endotracheal intubations through the Air-QILA were successful in 38 children in first attempt and 12 children required second attempt. In the remaining 10 children, where blind endotracheal intubation through the Air-QILA remained unsuccessful, conventional laryngoscopy was performed. In supine and lateral positions, Grade 1 glottic view was seen in 41 and 38 of total 60 patients, respectively. Turning of all children from supine to lateral decubitus position resulted in the deterioration of grading of glottic view in eight children and improvement in two children (P = 0.001). CONCLUSION: The Air-QILA is an easy to place supraglottic airway device with excellent airway seal and low airway morbidity. It may be useful as a conduit for blind orotracheal intubation in supine position and can be used as an effective alternative to FOB in low resource settings.

Corneal Polishing After Pterygium Excision With Motorized Diamond Burr: A Randomized Control Trial.

PURPOSE: To evaluate outcomes of motorized diamond burr polishing versus manual polishing after pterygium excision. SETTING: Dr. Rajendra Prasad Center for Ophthalmic Sciences, New Delhi. DESIGN: A randomized, interventional observer-masked controlled trial. METHODS: Forty consecutive eyes underwent pterygium excision with fibrin, glue-assisted conjunctival autograft. In group 1 (20 eyes), polishing of the corneal bed was done using a crescent blade, and in group 2 (20 eyes), using a motorized diamond burr. RESULTS: There was no difference in the 2 groups with respect to mean age (P=0.08), gender (P=0.3), preoperative uncorrected visual acuity (UCVA) (P=0.45), best spectacle-corrected visual acuity (BCVA) (P=0.52), spherical equivalent (P=0.5), mean astigmatism (P=0.7), tear function tests like tear break-up time, tear film meniscus height, Schirmer I and II (P=0.6, 0.5, 0.7, 0.9 respectively), pterygium dimension (P=0.4), and conjunctival autograft size (P=0.24). Mean intraoperative surgical time was significantly more in group 1 (16.9 ± 2.85 min) as compared with 12.25 ± 1.88 min in group 2 (P=0.0001). Postoperatively, there was a statistically significant reduction in astigmatism and improvement in UCVA, BCVA, spherical equivalent in all eyes. No difference was found in mean epithelial defect healing time, UCVA, BCVA, astigmatism, tear film break-up time, Schirmer I and II, and tear meniscus height at 6 months between 2 groups; however, significantly better UCVA was found in group 2 at 3 months (P=0.04). Surgically induced astigmatism (SIA) was significantly more in group 2 as compared with group 1 at 6 months (P=0.0006). CONCLUSIONS: Motorized diamond burr polishing of the corneoscleral bed during primary pterygium excision in comparison with manual polishing requires significantly lesser surgical time with better UCVA, decreased astigmatism, and greater SIA at 6 months, which indicates greater astigmatic correction.

Comparison of conventional infrainguinal versus modified proximal suprainguinal approach of Fascia Iliaca Compartment Block for postoperative analgesia in Total Hip Arthroplasty. A prospective randomized study.

Fascia Iliaca Compartment Block (FICB) has been widely used as a postoperative analgesic adjunct to opioids for total hip arthroplasty (THA), either by the conventional infrainguinal approach or the modified proximal suprainguinal approach irrespective of any specific advantage of one over the other. This study was conducted to compare the analgesic efficacy of the two techniques of FICB for postoperative analgesia. The 40 patients scheduled for THA were recruited for Intervention (s) and randomized to receive FICB either by suprainguinal approach (group S) or infrainguinal approach (group I) for postoperative analgesia with 40 ml of 0.2% bupivacaine, in addition to postoperative patient controlled analgesia (PCA) with morphine. Visual analogue scale (VAS) and PCA morphine consumption was used to assess the postoperative pain at 3, 6, 12 and 24 hours. The primary outcome was cumulative PCA morphine consumption in 24 hours. The pain intensity as measured by VAS scores showed significant reduction of intensity at 6 hours post block in group S as compared to group I (median [IQR]; 2[0-3]; 3[2.25-3]; p = 0.001) but, there was no significant difference in VAS at 12 and 24 hours. Postoperatively, there was significant difference in time to first PCA morphine demand (356.28 ± 33.32 vs 291.48 ± 37.17, p = < 0.001, respectively) in-group S vs. group I. The postoperative morphine consumption was also significantly less in group S compared to group I at 6, 12 and 24 hours and the cumulative morphine consumption in 24 hours (6.95 ± 2.14 vs 10.50 ± 2.24, p = < 0.001 respectively) was also less. In conclusion, in THA, suprainguinal approach of FICB has a superior postoperative analgesic efficacy compared to infrainguinal approach of FICB along with significantly less morphine consumption in first 24 hours.

Perioperative management of a patient of Rubinstein-Taybi syndrome with ovarian cyst for laparotomy.

Rubinstein-Taybi syndrome (RTS) is a multisystem involvement disease. These children may present for various surgeries of different systems. Due to multisystem involvement, perioperative management of such patients poses peculiar challenges for the anesthesiologists. We report the successful anesthetic management of a patient with RTS with tonsillar hypertrophy grade III scheduled for ovarian cystectomy.

Comparison of subarachnoid block with bupivacaine and bupivacaine with fentanyl on entropy and sedation: A prospective randomized double-blind study.

BACKGROUND AND AIMS: We studied the state entropy to monitor the sedative effect of subarachnoid block (SAB) using bupivacaine alone or combination of bupivacaine and fentanyl. The effect of use of fentanyl via the subarachnoid route on the sedation level was also studied using the entropy scores and the decrease in the requirement of propofol used as an adjuvant sedative drug. MATERIALS AND METHODS: In this prospective randomized double-blind study, 30 patients of age 18-70 years requiring SAB were enrolled for the study. Patients with any known allergy to study drugs, contraindication for SAB, obesity, neurological or psychiatric disease on concurrent medication and refusal were excluded from the study. Patients were randomly allocated into two groups: Group C: SAB was administered with 2.5 mL (12.5 mg) of 0.5% hyperbaric bupivacaine; Group D: SAB was administered with 2.5 mL of 2 mL (10 mg) of 0.5% hyperbaric bupivacaine and 0.5 mL (25 µg) fentanyl. Propofol infusion was started if the state entropy (SE) value was ≥75, at the rate of 100 µg/kg/min till the SE value reaches in the range of 60-75 (recorded as onset time). Thereafter the infusion rate was titrated to maintain SE value between 60 and 75. The level of sedation was measured with SE and Ramsay sedation (RS) scale. RESULTS: The demographic profile and baseline parameters, were comparable in two groups (P > 0.05). After SAB, decrease in SE and response entropy was noted in both the groups and fall was significant in Group D (P < 0.0001). The total propfol required in thew two groups were comparable being 3.97 ± 2.14 mg/kg in Group C and 3.41 ± 2.34 mg/kg in Group D (P = 0.342). The change in the mean RS values was from 1.17 ± 0.38 to 1.69 ± 0.47 in Group D (P = 0.06), whereas in Group C it was from 1.03 ± 0.18 to 1.43 ± 0.50 (P = 0.041) within 20 min of SAB. CONCLUSION: Subarachnoid block causes sedation per se, but the level of sedation is not clinically significant and the sedation caused is not enough to avoid sedative agents for allaying anxiety in patients intraoperatively. The sedative effect of SAB was enhanced by adding intrathecal fentanyl probably because of better quality of SAB. SE showed good correlation with RS scaling system.

Analgesic efficacy of classical thoracolumbar interfascial plane block versus modified thoracolumbar interfascial plane block in patients undergoing lumbar disc surgeries: A comparative, randomised controlled trial.

Background and Aims: We compared classical (medial) and modified (lateral) thoracolumbar interfascial plane block (TLIP) with only general anaesthesia (GA) using multimodal analgesia in patients undergoing lumbar disc surgeries. Methods: In this study, 100 patients aged 18-70 years were randomised to Group cTLIP (conventional TLIP block with 20 mL of 0.25% ropivacaine with GA), Group mTLIP (modified TLIP block with 20 mL of 0.25% ropivacaine with GA), and Group C (only GA using multimodal analgesia). The primary outcome was to assess the total peri-operative opioid consumption in the first 24 h. The secondary outcomes were to assess pain score upon arriving in the post-anaesthesia care unit, time to first analgesic need after surgery, post-operative opioid consumption in 24 h, and incidence of nausea and vomiting. Results: The total peri-operative opioid consumption in Group cTLIP (507.58 (258.55) µg) and Group mTLIP (491.67 (165.39) µg) was significantly lower than that in Group C (1225.4 (237.03) µg); (P < 0.001). However, it was comparable between groups cTLIP and mTLIP (P = 0.767). Pain score was comparable in groups cTLIP and mTLIP. It was significantly lower than Group C (P = 0.001). Rescue analgesia was needed in all (100%) patients of Group C but in only 15.2% of patients of the cTLIP and mTLIP groups. No patient in groups cTLIP and mTLIP complained of nausea and vomiting in the first 24 h, whereas it was significantly higher (61.8%) in Group C (P = 0.001). Conclusion: The analgesic effect of the modified TLIP block was not superior to the conventional TLIP block. Both techniques provided the same intra-operative and post-operative analgesia for lumbar disc surgeries.

Ultrasound-guided suprainguinal fascia iliaca block to position the patient for neuraxial anaesthesia in acetabular surgery - a randomized controlled pilot study.

INTRODUCTION: Neuraxial anaesthesia is a common choice for most hip and lower limb operations. Pain associated with positioning is often a deterrent, and the vast literature suggests different regional blocks and opioids for these patients. Patients with acetabular fractures may experience increased pain, and thus are more difficult to position for the neuraxial block. We conducted a randomized controlled pilot study to assess and compare the analgesic efficacy of ultrasound-guided suprainguinal fascia iliaca block (SFICB) versus systemic fentanyl to facilitate positioning for combined spinal epidural (CSE) anaesthesia in patients undergoing acetabular fracture surgery. MATERIAL AND METHODS: Twenty patients referred for surgical repair of acetabular fractures were randomly assigned to receive either ultrasound-guided SFICB (group B) or intravenous fentanyl (group F). Changes in visual analogue scale (VAS) scores in supine and sitting position, improvement in sitting angle (SA), positioning quality, rescue analgesic requirement, total opioid consumption, comfort VAS scores, and complications were noted to compare both groups. RESULTS: The post-intervention VAS score in the sitting position was significantly lower in group B than in group F (5.9 ± 2.1 vs. 3.5 ± 1.5, P = 0.01). Group B also had more significant improvement in SA (27.5° (20.75-36.5°), in comparison to group F (10 (5-18.75), P = 0.006). The positioning quality was better in group B, with 70% of patients achieving an optimal position compared to only 10% in group F ( P = 0.02). CONCLUSIONS: Ultrasound-guided SFICB, as compared to systemic fentanyl, provided better analgesia and helped to achieve a better and more comfortable position to perform the neuraxial block.

Delayed resolution of inflammatory response compared with clinical recovery in patients with acute exacerbations of chronic obstructive pulmonary disease.

BACKGROUND AND OBJECTIVE: The temporal profile of inflammatory markers during acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and their relationship to clinical response are not well characterized. The aim was to assess the changes in levels of inflammatory markers in AECOPD and correlate these with clinical and laboratory indices of recovery. METHODS: Serum levels of C-reactive protein (CRP), interleukin (IL)-6 and fibrinogen were measured in patients with AECOPD within 24 h of hospitalization and pre-discharge (stable state). RESULTS: Ninety-seven patients were evaluated (79 males; mean (SD) age, 61.4 (10.3) years). Eighty eight (90.7%) were current or former smokers, with a median consumption of 15 (0-75) packs/year. The median duration of COPD was 8 (2-25) years. Forty-six patients (56.9%) required mechanical ventilation for a median of 5 days (1-34) while in hospital. The median duration of hospital stay was 13 days (1-77). At reassessment before planned discharge, the levels of dyspnoea, leucocyte counts, erythrocyte sedimentation rate, creatinine, partial pressure of oxygen, and albumin normalized. The levels of CRP, IL-6 and fibrinogen reduced significantly but did not reach the normal range. Changes in IL-6 and fibrinogen levels correlated significantly with the acute physiologic assessment and chronic health evaluation II score, smoking history, blood pressure and leucocyte counts. Baseline IL-6 and fibrinogen levels significantly predicted a prolonged duration of mechanical ventilation. CONCLUSIONS: During AECOPD, the inflammatory response lags behind clinical and biochemical improvement. Fibrinogen and IL-6 are potentially useful markers for monitoring clinical response following an acute episode.

Ocular Chlamydia trachomatis infections in patients attending a tertiary eye care hospital in north India: a twelve year study.

BACKGROUND & OBJECTIVES: Ocular infection with Chlamydia trachomatis is a major public health problem in densely populated countries like India. The true prevalence of such infections is uncertain due to insufficient data available from India. The aim of this study was to do a retrospective analysis of C. trachomatis eye infections in patients attending the outpatient department of Dr Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, over a period of 12 years. METHODS: From 1997 to 2008, the Chlamydia laboratory received conjunctival swabs from 1281 consecutive patients for C. trachomatis detection after thorough clinical examination. Specimens were subjected to direct fluorescent antigen detection assay using monoclonal antibody based commercial kit to detect the presence of C. trachomatis antigen. RESULTS: Antigen positivity varied between 22-28 per cent. Children below 11 yr and people above the age of 60 yr showed comparatively higher antigen positivity (25.7 and 27.8%, respectively). As compared to males significantly (P<0.05) higher number of females in the age group of 31-60 yr were positive for C. trachomatis antigen. Patients with the clinical diagnosis of follicular/allergic conjunctivitis and trachoma showed higher rate of antigen positivity. INTERPRETATION & CONCLUSIONS: Northern India having dry and arid climatic conditions in most parts of the year was considered in the past as one of the trachoma hyper-endemic foci. The study indicated that laboratory proven C. trachomatis eye infection still persisted in this part of the country throughout the study period of 12 years.
