A prospective observational study of injection pain in children with medium plus long chain triglyceride and long chain triglyceride propofol premixed with lignocaine
Background and Aims: Propofol injection pain is an unresolved problem in children. Although medium and long chain triglyceride (MCT-LCT) propofol has shown promising results in adults, its efficacy in children is not proven. In a prospective observational study the incidence and severity of pain with MCT-LCT and LCT propofol in children was compared. Methods: After obtaining approval from the Institutional Ethics Committee, 170 children (age group 6 months to 8 years) scheduled for various surgeries were included in this study. Following standard pre-medication, propofol 1% either LCT or MCT-LCT in a dose of 2–4 mg/kg along with preservative-free lignocaine (2% lignocaine 1 mg in propofol 10 mg) was administered. The primary objective was to study injection pain on scale of 0–6. For children ≤2 years doubling of motor event score (0–3) and for children >2 years, addition of motor (0–3) and verbalisation scores (0–3) were considered. Mann–Whitney U test was used for statistical analysis. Results: MCT-LCT group had lower incidence of pain (17 patients (20%) versus 35 patients (35.3%), P = 0.026) and severe pain (zero patients (0%) versus six patients (7.1%), P = 0.029) as compared to LCT group. MCT-LCT group had significantly lower mean rank of motor (79.65 versus 91.35), verbal (77.29 versus 90.79) and total score (77.76 versus 93.24) as compared to LCT group (P = 0.037, 0.002, and 0.009, respectively). Conclusion: MCT-LCT propofol is associated with significantly lower injection pain as compared to LCT propofol in children, when both are combined with lignocaine
Comparison of maintenance, emergence and recovery characteristics of sevoflurane and desflurane in pediatric ambulatory surgery
Background and Aims: Increasing number of pediatric ambulatory surgeries are being carried out in general anesthesia using supraglottic airways (SGAs). Literature comparing sevoflurane and desflurane for the maintenance of SGA-based anesthesia is limited. Hence, we planned this prospective randomized study to compare the maintenance, emergence and recovery characteristics of sevoflurane and desflurane for pediatric ambulatory surgery.
Material and Methods: Sixty children aged 6 months to 6 years posted for short surgical procedures were enrolled into the study. Anesthesia was induced with intravenous propofol (maximum 4 mg/kg), SGA was inserted, and children were randomized to receive sevoflurane or desflurane for the maintenance of anesthesia. No muscle relaxants were administered, and all children received caudal block and rectal paracetamol suppository. Demographic data, perioperative hemodynamics and adverse events, emergence and recovery characteristics, postoperative pain, and emergence agitation (EA) were recorded. Data were analyzed using SPSS (version 16.0, IBM Corporation, Armonk, New York, USA). P < 0.05 was considered statistically significant.
Results: Demography, perioperative hemodynamics, and duration of inhalational anesthesia were comparable between two groups. There were no respiratory adverse events in either group during maintenance. Time to awakening and time to removal of SGA were shorter with desflurane (5.3 ± 1.4 and 5.8 ± 1.3 min) than sevoflurane (9.1 ± 2.4 and 10.0 ± 1.6 min) (P < 0.0001). Recovery (steward recovery score = 6) was faster with desflurane (18 ± 8.4 min) than sevoflurane (45.3 ± 9.7 min) (P < 0.001). The incidence of EA was 16.7% with desflurane and 10% with sevoflurane (P = 0.226).
Conclusion: Desflurane provides faster emergence and recovery in comparison to sevoflurane when used for the maintenance of anesthesia through SGA in children. Both sevoflurane and desflurane can be safely used in children for lower abdominal surgeries

Current practice patterns of supraglottic airway device usage in paediatric patients amongst anaesthesiologists: A nationwide survey
Background and Aims: Supraglottic airway devices (SGADs) are increasingly being used for airway management in paediatric patients undergoing general anaesthesia. This survey was designed to assess the nationwide practice patterns of SGAD usage in paediatric patients. Methods: A questionnaire of 28 questions was circulated amongst 16,532 members of the Indian Society of Anaesthesiologists through online survey engine Google Forms® and served manually to 500 delegates attending the Asian Society of Paediatric Anaesthesiologists conference 2017. Percentage, mean and standard deviation were calculated using Microsoft Excel 2016 (Redmond, WA, USA). Results: Four hundred and five (2.3%) valid responses were obtained. The most commonly used device was i-gel© (60.74%). Three hundred and four (75.06%) respondents had access to second-generation SGADs. Second-generation devices (60.74%) were more commonly used than first-generation devices (39.26%). Anaesthesiologists utilised SGADs in various challenging scenarios such as in the difficult airway (53.33%), remote locations (55.47%), ophthalmologic (38.77%) and long-duration surgeries (17.53%). Sixty per cent respondents did not use SGADs in laparoscopic surgery. Disposable SGADs were reused by 77.28% respondents. Oropharyngeal seal and intracuff pressures were not measured by 86.91% and 56.92% respondents, respectively. Difficulty in size selection (84.19%), securing position (82.22%) and maintaining unobstructed ventilation (78.76%) were common problems encountered while using SGADs. Conclusion: Although there is a widespread use of second-generation SGADs in Indian paediatric anaesthesia, safe practices such as using capnography, measurement of oropharyngeal seal pressure, cuff pressure and appropriate disinfection are lacking
