Objective To assess safety and efficacy of a novel intubation laryngeal mask airway (ILMA) during the recovery period following supratentorial tumour surgery. Methods Patients who underwent supratentorial tumour surgery at our centre from January 2012 to December 2016 were eligible for this prospective randomised, parallel group study. We developed a novel ILMA using closely fitting laryngeal masks (No. 4/5) with 7.0/7.5 mm endotracheal tubes (ETT) plus screw fixators and anti-pollution sleeves. Results In total, 100 patients were intubated with the novel ILMA and 100 the ETT. There were no differences between groups in haemodynamic variables, oxygen saturation, exhaled CO2, or bispectral index all recorded during the 72-hour recovery period. However, there were significantly fewer incidences of coughing, less fluid drainage and lower haemoglobin levels in surgical fluid in the ILMA group compared with the ETT group. Conclusion Our novel ILMA device was associated with reduced coughing, fluid drainage and blood in surgical drain during the recovery period following supratentorial tumour surgery.

Background: I-gel, the novel Supraglottic airway device, is easier to insert, has improved stability after insertion with reduced tissue compression.The study aims to compare the efficacy of I-gel with classic Laryngeal Mask Airway in the paediatric population.Methods: A randomised parallel group study was done in Department of Anesthesiology, Kanti Children Hospital, Kathmandu for a period of three months. I gel and classic LMA was compared based on leak airway pressure, time of insertion and ease of insertion.Results: Age and weight are comparable among groups. Compared to cLMA, I-gel provides a better leak pressure seal (16.40+-3.42 vs. 23.11+- 6.17 cm of H2O, p 0.027), faster time of insertion (19.42+-4.40 vs. 29.84+-7.70 seconds, p-0.02) and similar ease of insertion (p-0.571).Conclusions: I-gel compared to classic Laryngeal Mask Airway provides better resistance to leak airway pressure, faster time of insertion with comparable ease of insertion.

Abstract BackgroundAlthough endotracheal tube is preferred for airway management during laparoscopic percutaneous extraperitoneal closure for inguinal hernias, laryngeal mask airway may also be used. However, few studies have reported the usefulness of laryngeal mask airway during laparoscopic percutaneous extraperitoneal closure. Our study aims to report the advantages of laryngeal mask airway versus endotracheal tube during laparoscopic percutaneous extraperitoneal closure for inguinal hernia in pediatric day surgery.MethodsThe records of 56 patients (Group I, endotracheal tube; Group II, laryngeal mask airway) treated for inguinal hernia using laparoscopic percutaneous extraperitoneal closure between November 2018 and December 2019 were retrospectively reviewed. The duration of anesthesia; changes in hemodynamics (heart rate and systolic/diastolic blood pressure), end-tidal carbon dioxide, and bispectral index; and postoperative complications were analyzed.ResultsGroups I and II had 39 and 17 patients, respectively. The duration of anesthesia and surgery and changes in hemodynamics and bispectral index were similar between the two groups. Induction and recovery times were significantly shorter and changes in end-tidal carbon dioxide were more significant in Group II (p < 0.05). The incidence of sore throat and nausea was higher in Group I (p < 0.05).ConclusionsLaryngeal mask airway was equivalent to endotracheal tube in terms of performance during laparoscopic percutaneous extraperitoneal closure, although induction and recovery were achieved sooner in laryngeal mask airway, with a lower incidence of sore throat and nausea.Trial RegistrationNot applicable

Background Propofol and sevoflurane display additivity for gamma-aminobutyric acid receptor activation, loss of consciousness, and tolerance of skin incision. Information about their interaction regarding electroencephalographic suppression is unavailable. This study examined this interaction as well as the interaction on the probability of tolerance of shake and shout and three noxious stimulations by using a response surface methodology. Methods Sixty patients preoperatively received different combined concentrations of propofol (0-12 microg/ml) and sevoflurane (0-3.5 vol.%) according to a crisscross design (274 concentration pairs, 3 to 6 per patient). After having reached pseudo-steady state, the authors recorded bispectral index, state and response entropy and the response to shake and shout, tetanic stimulation, laryngeal mask airway insertion, and laryngoscopy. For the analysis of the probability of tolerance by logistic regression, a Greco interaction model was used. For the separate analysis of bispectral index, state and response entropy suppression, a fractional Emax Greco model was used. All calculations were performed with NONMEM V (GloboMax LLC, Hanover, MD). Results Additivity was found for all endpoints, the Ce(50, PROP)/Ce(50, SEVO) for bispectral index suppression was 3.68 microg. ml(-1)/ 1.53 vol.%, for tolerance of shake and shout 2.34 microg . ml(-1)/ 1.03 vol.%, tetanic stimulation 5.34 microg . ml(-1)/ 2.11 vol.%, laryngeal mask airway insertion 5.92 microg. ml(-1) / 2.55 vol.%, and laryngoscopy 6.55 microg. ml(-1)/2.83 vol.%. Conclusion For both electroencephalographic suppression and tolerance to stimulation, the interaction of propofol and sevoflurane was identified as additive. The response surface data can be used for more rational dose finding in case of sequential and coadministration of propofol and sevoflurane.
