Background and Objective: Acute pain services (APSs) in schema to its name primarily aim to manage acute postoperative pain. A meticulous and comprehensive APS leads to the prevention of acute pain developing into persistent chronic postsurgical pain. Good post operative pain relief helps in reduction of postoperative pulmonary complications. While a meaningful communication with the patient, assessment of general well being, facilitates eary discharge and functional recovery, thereby significantly contributing to the overall quality of recovery of the patient in the perioperative period. Methodology: An Anesthesia Consultant led APS team in our institute is responsible for daily clinical rounds. Effective communication with the patients facilitated early detection of detection of additional complaints such as restlessness, throat pain, nausea, vomiting, shoulder tip pain, increased drain output, urine retention, wound soakage and constipation to name a few. We could look beyond acute pain management. Results: One-year data from March 2023 to March 2024 were audited and subsequently findings were noted. Conclusion: APSs are an integral part of anesthesia management, primarily aiming at the management of perioperative pain in the best possible way. However, our study revealed other important aspects of this service, which could aid us in improving our perioperative outcomes.

Background and Aims: Rapid Sequence Induction (RSI) is an established technique to secure the airway in patients who are at risk of aspiration. The practice of RSI in the pediatric population is highly variable due to numerous patient factors. We conducted a survey to find the prevalent practices and adherence of anesthesiologists to the practice of RSI in different pediatric age groups and whether it differs with the experience of the anesthesiologist or the age of the child. Material and Methods: The survey was conducted among residents and consultants attending the pediatric national anesthesia conference. The questionnaire consisted of 17 questions on anesthesiologist's experience, adherence, conduct of pediatric RSI, and the reason for nonadherence. Results: The response rate was 75% (192/256). Anesthetists having less than 10 years of experience adhered to RSI more often as compared to respondents with more experience. Succinylcholine was the most commonly used muscle relaxant for induction, with use increasing in higher age groups. The application of cricoid pressure increased with increasing age groups. Anesthetists with >10 years of experience used cricoid pressure more often in age groups of

Background and Aims: A definitive cutoff of inferior venacava (IVC) diameter in expiration (dIVCmax) and inferior vena cava collapsibility index (IVCCI) for predicting general anaesthesia associated hypotension (GAAH) is not yet determined. Primary objective of this study was to determine the correlation of dIVCmax and IVCCI, with GAAH. Other objectives were to determine the correlation of these IVC parameters with preoperative fasting duration, temperature and humidity. The correlation of dIVCmax with patient demography was also studied. Methods: A total of 110 adult patients undergoing elective surgery under general anaesthesia were included in the study. IVC ultrasonography was done in the preoperative room, 20 to 30 minutes before shifting the patient to the operating room. Hypotension at (hypo@) 2 minutes and 10 minutes after administering vecuronium was recorded. Results: Hundred and seven patients were analysed. A significant positive correlation was present between patient height and dIVCmax (ρ = 0.25, P = 0.009). Area under receiver operating characteristics curve was 0.595 (95% confidence interval (CI) 0.485–0.705) and 0.568 (95% CI 0.458–0.679) for dIVCmax and IVCCI for predicting hypo@2 min, with a diagnostic accuracy of 54% and 53%, respectively. dIVCmax ≤1.14 cm had a sensitivity of 31% and specificity of 87% in predicting GAAH. IVCCI ≥63.3% could predict GAAH with 31% sensitivity and 84% specificity. No significant correlation was found between preoperative IVC parameters and preoperative fasting or environmental factors. Conclusion: Both dIVCmax and IVCCI have poor diagnostic accuracy, with good specificity and low sensitivity in predicting GAAH. A steady formula for calculating baseline IVC diameter adjusted for patient demography is needed.

Background and Aims: Limited studies are available comparing diagnostic accuracy of various airway predictors in geriatric patients. We conducted this study with primary aim to evaluate and validate the predictive value of 'standard airway predictors' like modified Mallampati test, thyromental distance (TMD), sternomental distance, neck movement (NM), mouth opening (MO), dentition and 'new airway predictors' like upper lip bite test (ULBT), ratio of height to thyromental distance and thyromental height test (TMHT) for predicting difficult laryngoscopy in geriatric patients. Methods: This prospective, observational study was conducted on 140 patients above 65 years of age of either sex, scheduled for elective surgery under general anaesthesia requiring endotracheal intubation. The age, weight, height, body mass index (BMI) and airway parameters were recorded. The laryngoscopic view was assessed by modified Cormack-Lehane scale. Standard formulae were used to calculate validity indexes. Results: The incidence of difficult larygoscopy found in our study was 25%. The mean age of our study population was 69.37 ± 4.23 years. TMD exhibited the highest sensitivity (80%) and negative predictive value (NPV) (91.86%) as compared to other studied airway predictors. The positive predictive value (PPV) of ULBT was 100%. Moreover, ULBT exhibited highest accuracy (82.14%) and odds ratio (86.88) and high specificity (91.30%) for predicting difficult laryngoscopy in geriatric patients. NM and TMHT also exhibited high accuracy (77.85%, 77.14%) and PPV (59.09%, 52.94%). Conclusions: TMD and ULBT both showed good predictive value in diagnosing difficult laryngoscopy in geriatric patients. Furthermore, NM and TMHT also exhibited higher diagnostic accuracy in predicting difficult airway in these patients.

Introduction: The rationale for using an intraperitoneal route for instilling a drug, local anaesthetic or opioid is that the exposure of peritoneum to visceral nociceptive conduction provides additional mechanism of analgesia. Aim: To compare the effectiveness of intraperitoneal bupivacaine and nalbuphine for postoperative pain relief after laparoscopic cholecystectomy. Materials and Methods: The present study was a randomised clinical study in which 80 patients underwent laparoscopic cholecystectomy, received either bupivacaine (n=40) or nalbuphine (n=40) intraperitoneally. Each patient was monitored postoperatively, as per the institution protocol. Severity of pain was assessed using the Visual Analog Scale (VAS) at rest and at movement Immediately After Recovery (IAR), after one hour and every four hours thereafter. The time to first rescue analgesic was compared. The data analysis was carried out with unpaired Student’s t-test and Chi-square test using software Statistical Package for the Social Sciences (SPSS) 20.0 version. Results: The study included 35 males and 45 females, with a mean age of 42.8±7.1 years. Both groups were well-matched demographically. There was no significant difference in the Heart Rate (HR) or Mean Arterial Pressure (MAP) between the groups postoperatively. However, VAS score was significantly lower in nalbuphine group at one hour (2.52±0.640) as compared to bupivacaine group (2.88±0.791, p=0.028), but on movement at 16 hours it was lower in bupivacaine group (1.43±0.501), as compared to nalbuphine group (1.67±0.474, p=0.030). The mean time of first rescue analgesic in nalbuphine group was 20.25±7.983 minutes, while in bupivacaine group it was 26.9±6.95 minutes (p-value-0.0002). Postoperative Nausea and Vomiting (PONV) was significantly higher with nalbuphine (35% vs 12.5%). No other significant complication was noted in either group. Conclusion: Intraperitoneal instillation of nalbuphine is an effective and safe way to reduce postoperative pain in patients undergoing laparoscopic cholecystectomy.

Background and Aims: The role of cervical epidural analgesia in head and neck cancer surgery is not fully explored. The aim of this study was to evaluate cervical epidural analgesia in terms of opioid and anesthetic requirements and stress response in patients undergoing head and neck cancer surgery. Material and Methods: After institutional ethical committee approval and written informed consent, 30 patients undergoing elective head and neck cancer surgery were randomized into two groups: Group E (cervical epidural analgesia with general anesthesia), and group G (general anesthesia alone). In group E, an 18 gauge epidural catheter was placed at cervical (C) 6 – thoracic (T) 1 level. After test dose, a bolus of 10 ml of 0.2% ropivacaine was given followed by continuous infusion. Technique of general anesthesia and post-operative management was standardized in both the groups. Opioid and anesthetic drug requirement was observed. Blood glucose and serum cortisol levels were measured at baseline; post-incision and after surgery. Results: There was significant reduction in the requirement of morphine (P < 0.001), isoflurane (P = 0.004) and vecuronium (P = 0.001) in group E. Post-operative, blood glucose and serum cortisol levels were significantly reduced (P = 0.0153 and 0.0074, respectively). Early post-operative pain was reduced with the lesser requirement of post-operative morphine. Conclusions: The use of combined cervical epidural analgesia with general anesthesia reduces opioid, anesthetic drug requirement and stress response as compared to general anesthesia alone in patients undergoing head and neck cancer surgery.

Background and Aims: Preoperative airway assessment to predict patients with difficult laryngoscopy is always crucial for anesthesiologists. Several predictive tests have been studied by various authors in quest of finding the best airway predictor. Recently, a new airway predictor, thyromental height test (TMHT) has been reported to have good predictive value in assessing difficult airway. We conducted this study with primary aim to evaluate the diagnostic accuracy of TMHT and to compare it with other established airway predictors, such as ratio of height to thyromental distance (RHTMD), thyromental distance (TMD), and modified Mallampati test (MMT) for predicting difficult laryngoscopy. Material and Methods: This prospective, observational study was conducted in 550 patients of either sex aged >18 years scheduled for elective surgery under general anesthesia. The patients' airway was assessed preoperatively by two anesthetists. Standard anesthetic protocol was followed in all the patients. The laryngoscopic view was graded according to Cormack–Lehane scale. The receiver operating characteristic (ROC) curve was used to calculate the ideal cut off values for TMHT and RHTMD. Standard formulae were used to calculate validity indexes. Results: The incidence of difficult laryngoscopy was 10%. The cut-off value for TMHT and RHTMD were 5.1 cm and 19.5, respectively. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of TMHT were 78.18%, 93.94%, 58.90%, and 97.48%, respectively. The highest sensitivity, PPV, and NPV were observed with TMHT as compared with RHTMD, TMD, and MMT (P < 0.0001). Conclusions: TMHT is the best predictive test with highest accuracy and odds ratio for predicting difficult airway out of all predictive tests evaluated.

Background and Aims: Pre-operative fasting is a routine practice to minimise the risk of pulmonary aspiration. The leading societies of anaesthesia have adopted more liberal fasting guidelines to avoid the adverse effect of prolonged fasting. This survey was conducted to assess the knowledge, attitude and current practice of fasting guidelines among Indian anaesthesiologists and to analyse the reasons for non-compliance of these guidelines. Methods: A questionnaire consisted of 11 questions was distributed via 'Survey Monkey' software to 621 anaesthesiologists who attended the annual conference of the Indian Society of Anaesthesiologists held in Ludhiana, in 2016. American Society of Anaesthesiologists (ASA) practice guidelines for fasting were the standard of assessment. Results: The response rate to the survey was 52%. Of the respondents, 69% described correctly the practice guidelines to pre-operative fasting. Only seven percent respondents were aware of the benefits of liberalised fasting. More than 2/3rd of the respondents advised fasting as per ASA guidelines during pre-anaesthetic check-up (PAC). However, only about 50% respondents confirmed that these guidelines are actually followed in their institution. Not having control on scheduling of cases in operation theatre and poor knowledge of ward nurses and surgeons were the common reasons for non-compliance of these guidelines. Twenty four percent respondents did not use routinely any drug for aspiration prophylaxis. Conclusion: Majority of the respondents were aware of the ASA fasting guidelines. However, the implementation of the guidelines and knowledge regarding benefits of liberalised fasting is poor among respondents.
