Transfusion trigger in the critically ill with sepsis or septic shock: A prospective study.

Background & objectives: Current practice around transfusion trigger in critically ill sepsis patients is not clear. Moreover, any association of haemoglobin trigger and other transfusion parameters such as age of red blood cells (RBCs) at transfusion and number of units of RBCs transfused with mortality and other adverse outcomes need further assessment. Methods: In this prospective study, patients aged 18-70 yr and admitted to intensive care with a diagnosis of sepsis were included (n=108). Baseline demographic, clinical and laboratory parameters were noted and various transfusion data, i.e., haemoglobin trigger, number of units of RBCs and the age of RBCs were recorded. Following outcome data were collected: 28 and 90 day mortality, duration of mechanical ventilation, vasopressor therapy, intensive care unit (ICU) and hospital stay and requirement of renal replacement therapy. Results: Of the total 108 participants, 78 (72.2%) survived till 28 days and 66 (61.1%) survived till 90 days. Transfusion trigger was 6.9 (6.7-7.1) g/dl [median (interquartile range)]. On multivariable logistic regression analysis, acute physiology and chronic health evaluation (APACHE) II [adjusted odds ratio (aOR) (95% confidence interval {CI}): 0.86 (0.78, 0.96); P=0.005], cumulative fluid balance (CFB) [aOR (95% CI): 0.99 (0.99, 0.99); P=0.005] and admission platelet count [aOR (95% CI): 1.69 (1.01, 2.84); P=0.043] were the predictors of 28 day mortality [model area under the receiver operating characteristics (AUROC) 0.81]. APACHE II [aOR (95% CI): 0.88 (0.81, 0.97); P=0.013], CFB [a OR (95% CI): 0.99977 (0.99962, 0.99993); P=0.044] and transfusion trigger [aOR (95% CI): 3 (1.07, 8.34); P=0.035] were the predictors of 90 day mortality (model AUROC: 0.82). Interpretation & conclusions: In sepsis, patients admitted to the ICU, current practice suggests transfusion trigger is below 7 g/dl and it does not affect any adverse outcome including 28 day mortality.

To Assess the Technical Feasibility of Ultrasound Lumbar Sympathetic Block with Electrical Stimulation Needle in Out-of-Plane Needle Orientation: A Prospective Interventional Study.

OBJECTIVE: We describe the technical feasibility of a new technique of ultrasound lumbar sympathectomy validated by fluoroscopy. DESIGN: Prospective interventional study. SETTING: Pain block area. SUBJECTS: Thirty patients with peripheral arterial disease with pain at rest (numerical rating score [NRS] ≥3) were recruited. METHODS: In the lateral position, a curved probe (FUJIFILM SonoSite Edge, Bothell, WA, USA, 2-5 MHz) was placed transversely at the iliac crest. An electrical stimulation needle was inserted out of plane, below the lower pole of the kidneys, directed anterior to the vertebral body below. When the needle tip was not visualized, a current of 2.0 A was applied. Patients' quadriceps contractions, ultrasound psoas contractions, and bone contact guided needle placement, which was confirmed on fluoroscopy. Other parameters noted were the number of needle insertions, vertebral level, pain NRS at baseline and at 4 hours, 24 hours, 1 week, and 2 weeks after block, temperature rise, and any other complications. RESULTS: In all patients, the needle tip was correctly placed in one to three attempts. In 73% of patients, the needle tip was at L3. Baseline pain NRS was 8 (interquartile range 7-8), which decreased to 2 (interquartile range 2-3) at 1 week after the procedure, and it was maintained in this range until 2 weeks later. A temperature rise of >2ºC was noted in all patients. CONCLUSION: Ultrasound lumbar sympathectomy can be performed safely in patients with peripheral arterial disease by an out-of-plane approach in the lateral patient position with an electrical stimulation needle. Before injection of the drug, aspiration of blood should be ruled out in view of the possibility of aortocaval injection.

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.

Effect of airway device and depth of anesthesia on intra-ocular pressure measurement during general anesthesia in children: A randomized controlled trial.

BACKGROUND AND AIMS: Accurate measurement of intraocular pressure (IOP) under anaesthesia is essential for diagnosis and further management of pediatric glaucoma patients. However, depth of anaesthesia and use of airway device like laryngeal mask airway (LMA) or endotracheal tube can influence IOP values measured. We planned this study to compare change of IOP with facemask or LMA. Change of IOP at varying depth of anaesthesia was also assessed. MATERIAL AND METHODS: After Institutional ethical clearance and informed parental consent, 89 children of glaucoma aged 0-12 years were included in this prospective randomized controlled trial. The children were randomized to facemask (Group M) and LMA (Group L). Sevoflurane was the sole general anaesthetic used in both the groups and IOP were recorded after induction, at BIS 40-60, after LMA insertion (Group L), at BIS 60-80 and BIS more than 80. RESULTS: The IOP values did not differ significantly between the groups at BIS 40-60 and at BIS 60-80. Moreover, pre and post LMA insertion IOP values were also comparable in Gr L (p = 0.11). However, significant increase in IOP values were observed with increasing BIS values within each group. The mean IOP in Group M at BIS 40-60 was 13.41 ± 4.04 as compared to 14.18 ± 3.64 at BIS 60-80 (p = 0.003). There was a similar pattern observed in Group L, where mean IOP at BIS 40-60 & BIS 60-80 was 14.13 ± 4.90 and 15.52 ± 4.57 respectively (p < 0.001). CONCLUSION: Either facemask or classic LMA can be safely used as per anaesthesiologist's preference without any significant effect on IOP. BIS monitoring may be used during IOP measurement in paediatric glaucoma suspects for accurate assessment of IOP.

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.

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.

Comparison of air-Q and Ambu Aura-i for controlled ventilation in infants: a randomized controlled trial.

BACKGROUND: The air-Q is a new supraglottic airway device (SAD) and has been increasingly used as a primary airway device and as a conduit for tracheal intubation in children as well as in adults. This device has either performed equally or better than other SADs in children. The Ambu Aura-i is a commonly used SAD in children undergoing various short surgical procedures. However, limited literature is available evaluating the safety and efficacy of the air-Q and the Ambu Aura-i in small children. We, therefore, conducted this study to compare the clinical performance of these two airway devices in infants weighing up to 10 kg. Our hypothesis is that air-Q, due to its improved and larger cuff design will yield better airway seal pressures as compared with the Ambu Aura-i. METHODS: Sixty-four ASA I-II infants weighing <10 kg undergoing elective ophthalmic surgery were randomly assigned to receive either an air-Q or the Ambu Aura-i. After induction of general anesthesia (GA) and muscle relaxation, we measured oropharyngeal leak pressure (OLP) as the primary outcome. The secondary end points measured were time to insert, first insertion success rate, fiberoptic grade (FO) of laryngeal view and any other airway complications like trauma, laryngospasm, and desaturation. RESULTS: The air-Q ILA provided significantly higher OLP as compared with the Ambu Aura-i [20.2 ± 4.6 cm H2 O, CI 18.55-21.88; vs 16.2 ± 5.6 cmH2 O, CI 14.27-18.25, P = 0.003; mean difference 4 ± 1.29 cm H2 O, CI 1.41-6.58]. However, the Ambu Aura-i required significantly less time for its insertion (14.6 ± 2.8 s, CI 13.66-15.70; vs 16.3 ± 1.5 s, CI 15.75-16.86, P = 0.005; mean difference 1.625 ±  0.56 s, CI 0.48-2.76). There were no differences in first insertion success rate, FO view, and postoperative complications. CONCLUSION: We conclude that air-Q may be considered superior to Ambu Aura-i in infants for controlled ventilation as it provides higher airway sealing pressures.

Comparative Sonoanatomy of Classic "Short Axis" Probe Position with a Novel "Medial-oblique" Probe Position for Ultrasound-guided Internal Jugular Vein Cannulation: A Crossover Study.

BACKGROUND: Ultrasound (US)-guided short-axis approach for internal jugular vein (IJV) cannulation does not fully protect patients from inadvertent carotid artery (CA) puncture. Carotid puncture is not rare (occurring in up to 4% of all IJV cannulations) despite the use of US. OBJECTIVES: Compare the sonoanatomy of the "medial-oblique approach" probe position with the classic US-guided "short-axis" probe position, specifically: relation of internal CA and IJV; vertical and horizontal diameter of IJV; and degree of overlapping of IJV with CA. METHODS: One hundred consecutive patients between the ages of 18 and 50 years, both male and female, and American Society of Anesthesiologists Physical Status classification system (ASA PS) I-II undergoing elective surgery under general anesthesia were recruited in this prospective, randomized, crossover, parallel-group study. RESULTS: The transverse diameter of the IJV was found to be significantly higher in the medial-oblique probe position (p = 0.000, mean difference 0.43 cm; 95% confidence interval [CI] 0.34-0.52). The percentage of overlap was also significantly lower in the medial-oblique probe position (48.7 ± 10.7% in short-axis vs. 36.3 ± 13.2% in medial-oblique probe position; p = 0.000; mean difference 12.4%, 95% CI 9.1-15.8). However, there was no statistically significant difference in the anteroposterior diameter of the IJV between the two probe positions (1.11 ± 0.26 cm in short axis vs 1.07 ± 0.25 cm in medial oblique; p = 0.631). CONCLUSION: The medial-oblique probe position for IJV cannulation provides sonoanatomic superiority over the classic short-axis probe position. Further randomized, controlled trials may confirm the medial-oblique view's clinical benefit in the future.

Caudal bupivacaine and morphine provides effective postoperative analgesia but does not prevent hemodynamic response to pneumoperitoneum for major laparoscopic surgeries in children.

The use of a caudal block in laparoscopic surgery in children is limited to minor procedures like inguinal hernia repair, and intravenous opioids remain the analgesic modality of choice in major laparoscopic surgery. However, a caudal block is frequently performed at our institute even for laparoscopic surgery. Therefore, we planned to evaluate the analgesic efficacy of caudal bupivacaine and morphine in major laparoscopic surgery as compared to intravenous opioids. Our hypothesis was that a single-shot caudal block would increase the duration of analgesia and minimize the hemodynamic response to pneumoperitoneum. After institutional ethics committee clearance, data were collected for 65 ASA I-II children aged 6 months to 12 years who underwent laparoscopic surgery in the last 14 months. Demographic, surgical, and perioperative anesthetic and analgesic data were noted and analyzed. Twenty-four children received a caudal block with 0.25 % bupivacaine (1-1.25 ml/kg) with morphine (30-50 mcg/kg). In the caudal group, the time to first analgesic request was increased (165 vs. 45 min; p = 0.00) and tachycardia response to port site incision was less observed (33 vs. 63 % children; p = 0.019). Hemodynamic response to pneumoperitoneum was equal in both of the groups. Single-shot caudal injection of local anesthetic with morphine reduces port site skin incision response and increases the duration of postoperative analgesia but fails to prevent hemodynamic response to pneumoperitoneum.

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.

Anesthetic management of parturient with thoracic kyphoscoliosis, malaria and acute respiratory distress syndrome for urgent cesarean section.

The management of cesarean section in kyphoscoliotic patient is challenging. The respiratory changes and increased metabolic demands due to pregnancy may compromise the limited respiratory reserves in such patients. Presence of other comorbidities like malaria and respiratory tract infection will further compromise the effective oxygenation. We report a case of kyphoscoliosis along with malaria and acute respiratory distress syndrome for urgent cesarean section.

Comparison of performance and efficacy of air-Q intubating laryngeal airway and flexible laryngeal mask airway in anesthetized and paralyzed infants and children.

BACKGROUND: Flexible laryngeal mask airway is a commonly used supraglotic airway device (SAD) during ophthalmic surgeries. Air-Q intubating laryngeal airway (ILA) is a newer SAD used as primary airway device and as a conduit for intubation as well. Available literature shows that air-Q performs equal or better than other SADs in children and adults. However, limited data is available using air-Q in infants and small children <10 kg. So, our aim was 'To compare the performance and efficacy of these two devices in infants and small children'. Our hypothesis is that air-Q due to its improved cuff design will yield better airway seal pressures and improved laryngeal alignment as compared to flexible laryngeal mask airway. METHODS: ASA I­II infants and children weighing <10 kg, undergoing cataract or glaucoma surgery, were randomly divided into two groups of 25 each. After induction of anesthesia and muscle relaxation, we measured oropharyngeal leak pressure (OLP), fibre-optic (FO) view of glottis, first insertion success rate, time to insert, and any other complications. RESULTS: There was no difference between the groups in demographic data, first insertion success rate, time to insert, and postoperative complications. Air-Q provided significantly more OLP [21.1 ± 6.4 cmH2O vs 17.4 ± 4.1 cmH2O, P = 0.02] and better FO view of glottis (good view 84% vs 48%, P = 0.0016) as compared to flexible laryngeal mask airway. CONCLUSION: We conclude that air-Q is superior to flexible laryngeal mask airway in providing higher airway sealing pressures and better FO grade of laryngeal view in infants and children.

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. Therefore, SE may be used as reliable tool to titrate sedation in patients undergoing surgery under SAB.

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.

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.

Internal jugular vein cannulation: A comparison of three techniques.

CONTEXT: Ultrasound-guided internal jugular vein (IJV) cannulation is known for increasing success rate and decreasing rate of complications. The ultrasound image can be used as a real time image during cannulation or to prelocate the IJV before attempting cannulation. AIMS: This study compares both the ultrasound-guided technique with the classical anatomical landmark technique (central approach) for right IJV cannulation in terms of success rate, complications, and time for cannulation. SETTINGS AND DESIGN: A prospective, randomized, observational study was conducted at a tertiary care hospital. MATERIAL AND METHODS: One hundred twenty patients requiring IJV cannulation were included in this study and were randomly allocated in three groups. Number of attempts, success rate, venous access time, catheterization time, and complications were observed in each group. STATISTICAL ANALYSIS USED: Statistical analysis was performed using STATA-9 software. Demographic data were compared using one-way analysis of variance (ANOVA). Nonparametric data were compared using the Kruskall-Wallis test, and multiple comparisons were done applying The Mann-Whitney test for individual pairs of groups. Nominal data were compared by applying the Chi-square test and Fisher exact test. RESULTS: Successful cannulation (≤3 attempt) was achieved in 90.83% of patients without any statistical significant difference between the groups. Venous access time and catheterization time was found to be significantly less in both the ultrasound groups than the anatomical land mark group. Number of attempts and success in first attempt was similar between the groups. CONCLUSIONS: Both the ultrasound techniques are found to be better than the anatomical landmark technique. Further, ultrasound-guided prelocation was found to be as effective as ultrasound guided real-time imaging technique for right IJV cannulation.

Role of splenic artery partial embolization in a patient with portal hypertension and pancytopenia undergoing hysterectomy under anesthesia.

Management of a patient with portal hypertension and hypersplenism who is scheduled for elective surgery is a challenge for anesthesia providers. We report a case that was scheduled for elective surgery in which preoperative splenic artery embolization improved the hematologic parameters. A 32-year-old woman was scheduled for total abdominal hysterectomy for multiple fibroids and menorrhagia with pancytopenia. She also had diagnoses of chronic liver disease with cirrhotic changes, portal hypertension, and grade IV Manageesophageal varices with hepatosplenomegaly. In view of pancytopenia, splenic artery partial embolization was done preoperatively. Her hematologic parameters improved, and she underwent surgery under general anesthesia with intrathecal morphine analgesia, uneventfully. The condition of patients with portal hypertension with associated hypersplenism and pancytopenia who are scheduled for elective surgery can be optimized with preoperative partial splenic artery embolization.
