ABSTRACT
Background: Supraglottic devices have revolutionized the current practice of airway management. We compared the clinical performance of a recently introduced BlockBuster™ Laryngeal mask airway with i-gel® in adult patients under general anesthesia. Methods: Following Institutional ethical clearance, the present study was conducted on 62 patients belonging to American Society of Anesthesiologists physical status 1 and 2 of either sex in the age group of 20-60 years under general anesthesia. Patients were randomly assigned to i-gel® (I) and BlockBuster™ (B) groups (31 per group). Time for successful insertion, insertion success rate, ease of insertion, oropharyngeal leak pressures (OLPs), and complications were assessed. Results: Mean insertion time of device was less in Group I (13.52 ± 2.58 s) than that of Group B (14.10 ± 2.04 s), which was neither clinically nor statistically significant (P = 0.330). OLP in Group B (24.52 ± 2.77 cm of H2O) was found to be significantly higher compared to Group I (20.81 ± 2.56 cm of H2O) with P < 0.001. Overall insertion and first attempt success was similar (i-gel® 31/31 [100%] and 29/31 [93.5%] and BlockBuster™ 31/31 [100%] and 29/31 [93.5%], respectively). Ease of insertion (P = 0.684) and complications (P = 0.782) of both the devices were comparable. Conclusions: Both the devices are useful and effective for airway management in adult under general anesthesia. Having a high OLP and comparable insertion time, risk of aspiration may be further reduced with the use of BlockBuster™ in comparison to i-gel®.
ABSTRACT
BACKGROUND: A side effect of spinal anesthesia is post-dural puncture backache (PDPB), which is characterized by ongoing discomfort at the location of the spinal puncture without any radicular pain. This study aims to compare the incidence and severity of post-dural puncture back pain following spinal anesthesia by median versus paramedian technique in obese female patients. METHODS: A prospective randomized comparative study on 120 female patients, aged 20-50 years with a BMI of 30-40 kg/m2 and American Society of Anesthesiologists physical status II, scheduled for elective surgery under spinal anesthesia, was included in the study. Patients were randomly divided into two groups, with 60 patients in each group. Group P uses the paramedian approach for spinal anesthesia, and group M uses the midline approach for spinal anesthesia. RESULTS: Low back pain incidence was lower in group P than in group M at seven days, but at one month and after, its incidence remained the same in both groups. No difference in the severity of pain was observed. CONCLUSIONS: The occurrence of back pain in the first seven days of surgery was significantly more frequent with the median approach. The pain severity decreased as the time passed from day seven to three months of follow-up. There is no difference in the severity of pain with either approach at different intervals.
ABSTRACT
Background and Aims: Apprehension of pain due to a spinal needle is often a cause of anxiety and refusal. ShotBlocker provides non-painful physical stimulation, inhibiting pain perception. The vapocoolant spray contains ethyl chloride vapours, rapidly raising the skin temperature and hampering the transmission of noxious stimuli. The present study compared the effectiveness of the ShotBlocker device and the vapocoolant spray in reducing spinal needle-associated pain in primigravida women undergoing elective lower-segment caesarean section (LSCS). Methods: We enroled 144 primigravida women undergoing elective LSCS and were randomised to Group SB (the ShotBlocker device was firmly pressed over the skin, and the spinal needle was inserted through its slit), Group V (the vapocoolant spray was applied at the puncture site before spinal needle insertion), and Group C (received local infiltration before spinal anaesthesia (SA)). The groups were compared for needle-associated pain and patient satisfaction using a 10-point visual analogue scale (VAS) and a 3-point Likert scale. Results: The mean (standard deviation) [95% confidence interval (CI)] VAS scores of Group SB 3.85 (0.74) [3.64, 4.07] and Group V 3.04 (0.74) [2.83, 3.26] were significantly lower than that of Group C 5.19 (0.92) [3.28, 3.62]). On the Likert scale, the maximum number of patients in the vapocoolant group (64.6%) responded satisfactorily, while in the control group, the majority (62.5%) of participants responded dissatisfied (P < 0.001). Conclusion: Both the ShotBlocker and vapocoolant spray reduce needle puncture-associated pain before SA in primigravida patients undergoing elective LSCS. However, the vapocoolant spray is more beneficial in reducing spinal needle-associated pain than the ShotBlocker device.
ABSTRACT
INTRODUCTION: Investigations of preoperative oral carbohydrate (CHO) loading have primarily examined benefits among patients without diabetes. Preoperative CHO-rich beverages in general populations have resulted in reductions in insulin resistance after surgery, protein loss, metabolic derangements, and immune dysfunction. The aim of this study was to assess the effect of CHO loading in diabetic patients undergoing laparoscopic cholecystectomy. METHODS: Diabetic patients controlled on oral hypoglycemic agent were randomly divided into two groups: (1) Group T - this group will be given 50 g of maltodextrin before two hours of surgery; (2) Group C - this group will be kept nil per oral as per standard protocol. Blood sugar, serum insulin, serum cortisol, and insulin requirement were compared in both groups. RESULTS: Blood sugar levels of Group C were found to be significantly higher than that of Group T at six hours and 24 hours. In Group T, a rise in baseline serum insulin (8.94 ± 3.43 mIU/l) was observed at 24 hours (13.23 ± 5.71 mIU/l). A change of 4.29 ± 3.00 mIU/l in serum insulin level was observed. The change in baseline serum insulin levels was 47.99%. In Group C too, a rise in baseline serum insulin (6.27 ± 1.74 mIU/l) was observed at 24 hours (18.00 ± 5.34 mIU/l). A change of 11.73 ± 4.97 mIU/l in serum insulin level was observed. The change in baseline HOMA-IR (homeostatic model assessment for insulin resistance) levels in Group T was 53.66%. A rise (4.39 ± 1.63) in baseline HOMA-IR of Group C (1.65 ± 0.45) was observed at 24 hours (6.04 ± 1.76). The change in baseline HOMA-IR levels in Group C was 266.06%. CONCLUSIONS: CHO loading is observed to be beneficial in diabetic patients undergoing laparoscopic cholecystectomy. No adverse effects or an increased risk of aspiration were observed in the intervention group during the study period.
ABSTRACT
Introduction Listening to music is a safe and low-cost way to reduce preoperative anxiety among patients, but more research is needed to evaluate its effectiveness fully. Aims The aim of the study is to identify the effect of intraoperative music therapy on the visual analogue scale for anxiety (VASA) scores (VASA 1 and VASA 2) and patient satisfaction score (PSS) perioperatively. Methods In a study of 188 patients aged 40-70, those in group A (94 patients) listened to pre-approved music during their surgery for abdominal hysterectomy, while group B (94 patients) did not. Both groups wore noise-cancelling earphones. VASA was recorded before (VASA 1) and after (VASA 2) the surgery. PSS was recorded in the postoperative ward. Music preferences were kept confidential from the investigator recording the scores. Result The two groups of patients had similar demographic profiles and baseline characteristics. The VASA 1 of both groups was similar, with a mean value of 4.36 ± 1.13 for group A and 4.23 ± 1.05 for group B (p = 0.606). However, group A had lower VASA 2 (1.79 ± 0.83) than group B (3.77 ± 0.98). The difference was statistically significant (p < 0.001). The patient satisfaction score in group A was notably higher than those in group B. A total of 52 patients were highly satisfied in group A as compared to none in group B (p < 0.001), and a total of 42 patients were moderately satisfied as compared to eight patients in group B (p < 0.001). Eighty-six patients in group B were unsatisfied. Conclusion According to our research, playing specific music at the right volume can significantly lower anxiety levels and increase patients' satisfaction scores for those who have had abdominal hysterectomy surgeries.
ABSTRACT
Background and Aims: The Baska mask (BM) and the Ambu AuraGain (AAG) have shown promising results in recent trials but have not been compared. Therefore, we aimed to compare the clinical performance of the BM and the AAG for airway management of adult patients. Methods: In this randomised comparative study, patients aged 18-60 years and with an expected surgical duration of less than 2 h were enroled. Patients were randomly allocated to AAG (Group A, n = 37) and BM (Group B, n = 37) for airway management. After induction of anaesthesia, an allocated supraglottic airway device (SAD) was inserted. Oropharyngeal leak pressure (OLP), time taken to insert SAD, number of insertion attempts, leak fraction (LF), first-attempt success rate, overall success rate, ease of insertion, fiberoptic view of the glottis, and complications were compared. The data were analysed using Student's t-test, Mann-Whitney U test, and Fisher's exact tests. Results: Baseline and demographic characteristics were comparable. OLP (31.32 ± 2.59 versus 27.54 ± 1.32 cmH2O) was higher (P < 0.001), and LF (6.19% ± 1.20% versus 7.24% ± 1.72%) was lower (P = 0.003) in the BM group. First-attempt and overall success rate, time taken to insert, number of insertion attempts, ease of insertion, and fibreoptic view of glottis through the SADs were statistically similar between groups. However, the incidence of sore throat (P = 0.007) and cough (P = 0.028) was higher with AAG. Conclusion: Clinical performance of BM was better than AAG as the former had higher OLP, lower LF and complications.
ABSTRACT
Background: Patients with thyroid swelling are anticipated difficult airway due to the anatomical complications associated with it leading to restricted neck movements and distorted laryngeal anatomy. The aim of this randomized prospective study was to compare Macintosh laryngoscope and Airtraq video laryngoscope for endotracheal intubation in patients with thyroid swelling. Methods: Eighty adult American Society of Anesthesiologist (ASA) grades I-II patients were taken and randomly divided into two groups of 40 patients in each. After induction of general anesthesia, tracheal intubation was done with either of the technique using a flexometallic tube. Time taken for intubation, hemodynamic variations during and after intubation, any optimization maneuver used during intubation, Cormack-Lehane score, Percentage of Glottic Opening (POGO score), Intubation Difficulty Score (IDS), and postoperative airway symptoms were noted. Results: Mean time required for intubation with Airtraq was more than Macintosh; P = 0.003. But Cormack-Lehane score, IDS score, and POGO score were better in the Airtraq group. Hemodynamic variations in both groups were comparable. Optimization maneuver required and postoperative airway symptoms were more in the Macintosh group. Conclusion: In patients with thyroid swelling, Airtraq video laryngoscope provides better visualization of the glottis, requires less manipulation during intubation, and less post-operative complications than Macintosh laryngoscope but requires significantly more time for intubation.
ABSTRACT
Background The purpose of this study was to compare the efficacy of continuous epidural infusion with intermittent bolus doses for labour analgesia using ropivacaine 0.2% and opioids. Methods In this study, 70 primigravida patients were randomly divided into two groups of 35 each. Both groups received a loading dose of 10ml of 0.2% ropivacaine and 1µg/ml fentanyl in 5ml incremental doses while monitoring blood pressure and heart rate. Subsequently, Group I received a continuous epidural infusion of 0.2% ropivacaine with fentanyl at 10ml/hr, while Group II received 10 ml of 0.2% ropivacaine with fentanyl in bolus form every hour manually, with the first dose given after one hour of the initial loading dose. A rescue bolus dose of 5ml of 0.2% ropivacaine was given in both groups when they complained of breakthrough pain (VAS score >3). An additional 5ml bolus dose was given in both groups at the time of crowning. The blood pressure, heart rate, and severity of pain using the visual analogue scale (VAS) were assessed. Total drug volume utilized, the number of bolus doses, duration of the first and second stage of labour, rate of instrumental delivery and cesarean section, and neonatal Apgar scores were also recorded. Results The total volume of drugs consumed and the number of boluses required for breakthrough pain were both significantly lower in Group II. There was a similar decrease in hemodynamic parameters (systolic blood pressure, diastolic blood pressure, and mean arterial pressure) from baseline in both the groups with no significant difference between them. The onset of analgesia was significantly faster in Group I with both groups achieving optimum analgesia (VAS ≤ 3) within 20 minutes of the loading dose. Maternal motor blockade scores, the duration of the first and second stage of labour, the rate of instrumental delivery, cesarean section, and neonatal Apgar scores, did not show any statistically significant difference between the two groups. Conclusion Both techniques, i.e. continuous epidural infusion and intermittent epidural boluses are effective for providing labour analgesia. But consumption of drugs and episodes of breakthrough pain was higher in the continuous infusion group (Group I).
ABSTRACT
Purpose: The behavior of trigeminocardiac reflex (TCR) is limited to few case reports only in maxillofacial surgery, especially for temporomandibular joint (TMJ) ankylosis cases. The present study aims to find out the incidence of bradycardia due to TCR during intraoperative forceful mouth opening in TMJ ankylosis patients. Materials and Methods: A prospective, unicentric observational study was conducted selecting those patients who were planned for osteoarthrectomy with interpositional gap arthroplasty under general anesthesia. Sixty cases of TMJ ankylosis were randomly selected from December 2018 to-03-2020. Predictor variables were patient age, gender, and type of ankylosis, and outcome variables were pulse rate, mean arterial blood pressure (MABP), and oxygen saturation level (SPO2). Data were recorded at baseline and during intraoperative mouth opening via heister jaw stretcher. A Chi-square test was used for testing the association between variables. P values were considered statistically significant at <0.05. Results: The sample size of 60 subjects has been divided into two age groups (10-19) years and (20-40) years. The mean standard deviation age of the patients was 18.32 ± 6.81 years. About 63.3% were male. Out of 60 cases, 14 patients developed bradycardia. The frequency of bradycardia was found 23.3%. According to logistic regression analysis, age and type of ankylosis were the significant predictors of bradycardia. Conclusion: We conclude that bradycardia due to TCR in TMJ ankylosis patients is not an uncommon entity. Incidences are more prevalent in the age group of 10-19 years and type IV bony ankylosis. Male had a high incidence of bradycardia though P value was nonsignificant.
ABSTRACT
BACKGROUND AND AIMS: The coronavirus disease -19 has changed various aspects of education and training in all fields, and e-learning has now become the preferred mode of training and teaching. The aim of this study was to assess the impact of online training and to overcome the limitations of e-learning. METHODS: A total of 176 medical officers (MOs) and 720 community health officers (CHOs) were trained in four batches by using seven training modules with online videos and lecture series. Each batch received two days of training. A pre-test and post-test were conducted which consisted of 25 multiple-choice questions of 4 marks each. There was no negative marking. Candidates obtaining >80 marks were declared as having passed. The results of the pre-test and post-tests were compared. RESULTS: There was remarkable improvement in the knowledge regarding critical care management after virtual training, as evidenced by the test results. None of the MOs scored more than 80% in the pre-test; however, 153 MOs scored more than 80% in the post-test. The average score improved from 47.82 (pre-test) to 89.05 (post-test). The difference was statically significant (P < 0.0001). Similarly, 123 CHOs scored more than 80% in the pre-test, while 378 CHOs scored more than 80% in the post-test. Improvement in average marks was also seen: 90.5 in the post-test as compared to 62.76 in the pre-test. The difference was statically significant (P < 0.0001). CONCLUSION: Online training is beneficial for many candidates from various locations within a short period. The interactive sessions after training are also helpful, and well-designed pre- and post-tests are adequate for assessment.
