Background: There is increasing use of laryngeal mask airway in children because of ease of insertion and minimal disturbances in cardio respiratory system and lesser risk of airway injury during perioperative period as compared to endotracheal tube. It is also simple, well-tolerated, safe, reusable, cost effective method of airway management in paediatric patients. Intravenous propofol (1%) is a preferred induction agent for LMA insertion till date, while sevoflurane, a halogenated volatile inhalational, non-irritating anaesthetist agent with pleasant odour is also suitable for inhalational induction of children. This study was carried out to study and compare clinical efficacy of propofol and sevoflurane for laryngeal mask airway (LMA) insertion in children undergoing short surgical procedures.Methods: In this study, total 100 children of ASA grade I/II of either sex with age group 3-8 years, weighing between 10-20 kg were enrolled. They were induced with either sevoflurane (group S) or intravenous propofol (group P) 3 mg/kg. Then appropriate size LMA was inserted. Various parameters like jaw relaxation and ease of insertion attempts required hemodynamic changes were noted and compared in two groups.Results: In group P, 94% patients and groups S, 90% patients had full jaw relaxation. The LMA insertion was easy in 98% patients in groups P and 94% patients in groups S. In 98% patients of groups P and 96% patients in groups S, LMA was inserted successfully in first attempt. The mean time required for LMA insertion was 19.16±5.29 seconds in groups P and 20.8±6.39 seconds in groups S. Both the groups were comparable with respect to haemodynamic changes observed which were transient and clinically not significant though statically significant.Conclusions: Both the groups showed comparable and satisfactory LMA insertion conditions, hence both can be routinely used for induction of anaesthesia in children.

Introduction: The Laryngeal Mask Airway (LMA) has gained extensive popularity for airway management during surgery. Propofol, the most commonly used induction agent for LMA insertion, causes significant haemodynamic changes. Sevoflurane has the potential to be as good an induction agent as propofol. Aim: To compare ease of insertion of classic LMA in patients undergoing elective surgery using intravenous propofol and inhalational sevoflurane. Materials and Methods: The study was a randomised clinical trial conducted in the Operation Theatres of Midnapur Medical College and Hospital, Medinipur, West Bengal, India, from August 2019 to July 2020. Eighty patients of American Society of Anaesthesiologists (ASA) physical status grade I and II, of both sexes, and aged between 18 years to 65 years were equally divided into two groups: group P (Propofol group) and group S (Sevoflurane group). Group P was given injection Propofol 2.5 mg/kg body weight and group S was given vital capacity breath induction with 8% sevoflurane and oxygen at 8 litres/min. Loss of Consciousness (LOC) was confirmed and induction time was noted for each group. After confirmation of ease of mouth opening, by an independent observer, LMA insertion was attempted. Ease of LMA insertion was assessed by a predefined 18 points table along with time to LMA insertion and number of attempts. Haemodynamic changes and adverse effects were also recorded. Chi-square test or Student’s t-test were used and a p-value ≤0.05 was considered as statistically significant. Results: With respect to age, sex and weight there were no significant differences between the two groups. Induction time was significantly less in group P (51.85±6.66 seconds) compared to group S (68.38±13.93 seconds) (p-value=0.0001), but LMA insertion time, number of attempts and overall ease of LMA insertion conditions according to the 18 points score were comparable between the two groups. Mean arterial pressure at certain points after induction was significantly less in group P (at 3 minute p-value=0.009 and at 5 minute p-value=0.007). Apnea was significantly more in group P (p-value=0.023). Conclusion: Sevoflurane was comparable to propofol for LMA insertion in respect of ease of insertion and insertion time. Although induction time was significantly less for propofol, sevoflurane offered better haemodynamic stability and lesser incidence of apnea.

Background: The increasing emphasis on day case anaesthesia has lead to the greater use of the laryngeal mask airway (LMA) as an alternative to intubation. Laryngoscopy and tracheal intubation are noxious stimuli, which cause a reflex increase in both sympathetic and sympathoadrenal activity that may result in tachycardia, hypertension and dysarrhythmias. Insertion of Laryngeal mask airway (LMA) is associated with less haemodynamic changes, minimal increase in intraocular and intracranial pressure and lower incidence of sore throat. Still its insertion requires sufficient depth of anesthesia to prevent airway reflex (gagging, coughing nd spasms). To insert LMA successfully propofol is the most frequently administered medication. But most of all recommend not using propofol singly for LMA insertion. Thiopental can’t suppress the upper airway reflexes as propofol but with low dose succinylcholine upper airway reflexes are attenuated so combination of thiopental sodium with succinylcholine may be another choice of drug.Objectives: This Prospective study was conducted to evaluate the effectiveness of Thiopental sodium and Succinylcholine for insertion of the LMA in comparison with Propofol.Methods: This interventional study was carried out in Sixty patients, aged 3-45 years who were scheduled for elective surgical procedure under general anaesthesia in ShSMCH. Patients were randomly assigned to two groups by odd and even number basis. In Group-1 (N1=30), LMA was inserted after induction with Thiopental sodium (5 mg/kg body weight i.v.) and Succinylcholine (0.5mg/kg i.v); in Group-2 (N2 = 30), the LMA was inserted with Propofol (2.5mg/kg i.v). Jaw relaxation, incidence of coughing- gagging , overall insertion condition and haemodynamic changes were observed.Results: Grade of jaw relaxation in Group-1 was Good in 93.3%, incomplete in 6.7% and 0% poor but in Group-2, 86.7% was good 10% incomplete and 3.3% was poor. Coughing occurred in 33.3% of patients in the Group-2 and there was only 10% in succinyl group (P=0.028) which is significantly higher in Group-2. Overall insertion condition in Group -1 was excellent in 86.7%, Good in 10% cases and poor in only 3.3% cases on the other hand in Group-2 excellent in 53.3%, Good in 33.3% cases and poor in only 13.3% cases (P=0.019).Conclusion: There was statistically significant difference in jaw relaxation in two groups and incidence of Gagging or Coughing is higher in Group-2. Overall insertion condition was significantly better in Group-1. We concluded that Thiopental sodium with low dose Suxamethonium is an effective alternative of Propofol.J Shaheed Suhrawardy Med Coll, June 2018, Vol.10(1); 11-15

General anaesthesia (GA) is most often indicated for category 1 (immediate threat to life of mother or baby) caesarean delivery (CD) or when neuraxial anaesthesia has failed or is contraindicated. Secure intravenous access is essential. Jugular venous cannulation (with ultrasound guidance) is required if peripheral access is inadequate. A World Health Organization surgical safety checklist must be used. The shoulders and upper back should be ramped. Left lateral table tilt or other means of uterine displacement are essential to minimize aortocaval compression, and a head-up position is recommended to improve the efficiency of preoxygenation and reduce the likelihood of gastric contents reaching the oropharynx. Cricoid pressure is controversial. In the United Kingdom, thiopental remains the induction agent of choice, although there is scant evidence upon which to avoid propofol. In pre-eclampsia, it is essential to obtund the pressor response to laryngoscopy with remifentanil or alfentanil. Rocuronium is an acceptable alternative to succinylcholine for neuromuscular blockade. Sugammadex offers the possibility of swifter reversal of rocuronium than spontaneous recovery from succinylcholine. Management of difficult tracheal intubation is focused on ‘oxygenation without aspiration’ and prevention of airway trauma. The Classic™ laryngeal mask airway is the most commonly used rescue airway in the United Kingdom. There is a large set of data from fasted women of low body mass index who have undergone elective CD safely with a Proseal™ or Supreme™ laryngeal mask airway. Sevoflurane is the most popular volatile agent for maintenance of GA. The role of electroencephalography-based depth of anaesthesia monitors at CD remains to be established. Intraoperative end-tidal carbon dioxide tension should be maintained below 4.0 kPa.
