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
Trigeminal neuralgia (TN) or tic douloureux is one of the commonest cause of fascial pain after 50 years of age. It is characterized by recurrent, episodic, lancinating pain over the distribution of trigeminal nerve. There is a lack of certainty regarding the aetiology and pathophysiology of TN. Evidence suggests that the likely etiology is vascular compression of the trigeminal nerve leading to focal demyelination and aberrant neural discharge. Secondary causes such as multiple sclerosis or brain tumors can also produce symptomatic TN. The treatment of TN can be very challenging despite the numerous options patients and physicians can choose from. This multitude of treatment options poses the question as to which treatment fits which patient best. For patients refractory to medical therapy, Gasserian ganglion percutaneous techniques, gamma knife surgery and microvascular decompression are the most promising invasive treatment options. Among them three common interventions commonly carried out by interventional pain physician to provide pain relief are balloon compression, Glycerol rhizolysis and RF rhizotomy.

Background: Dexmedetomidine is a newer adjuvant anesthetic agent which is gaining its popularity day by day in our perspective. As an anaesthetic adjuvant dexmedetomidine has been shown to provide good perioperative haemodynamic stability during laparoscopic surgeries. But still it is to be judged its efficacy as adjuvant agent in our aspect. Objective: To observe the haemodynamic effects of intravenous dexmedetomidine during laparoscopic cholecystectomy. Methods: Eighty(80) patients (ASA grade l and ll) who underwent laparoscopic cholecystectomy surgery were randomly selected and were scrutinized according to eligibility criteria.The selected patients were divided into two groups on even and odd number basis. Even number Group A (n=40): received a bolus dose of I.V dexmedetomidine 1μg/kg over 10 minutes before induction of Anesthesia and then I.V infusion of 0.5 μg/kg/hr as a maintenance infusion and odd number Group B(n=40): received a bolus dose of same volume of normal saline before induction of Anesthesia and infusion was continued during surgery. General anesthesia was administered in all patients using fentanyl, thiopentone, succinylcholine, nitrous oxide in oxygen, halothane and muscle relaxation maintained with vecuronium bromide. A pre-tested, observation based, peer-reviewed data collection sheet was prepared before study. Results: Intra-operative mean Heart rate of Group B patients were more higher than those of Group A patients and showed statistically significant differences (P=0.003). Mean arterial pressure of Group B patients were far more higher than Group A patients in different events of peroperative period which is statistically significant (P=0.001). Mean diastolic blood pressure in Group B was significantly higher than that of Group A (P=0.0001). Conclusion: Dexmedetomidine is an effective drug that can be used as adjunctive infusion in general anesthesia in an intention to stable the hemodynamic profile in the peroperative period of different surgeries. Specially in laparoscopic cholecystectomy some patients with cardiac risk become vulnerable after CO2 gas in sufflation which can be properly managed using Dexmedetomidine.
