A Comparison of Air-Q and I-Gel in Terms of Insertion Conditions and as Intubating Aids for Elective Surgeries under General Anaesthesia

BACKGROUND&#x0D; Supraglottic airway devices (SAD) like air Q and I-Gel are widely used in place of tracheal intubation for general anaesthesia. The present study was undertaken to compare the insertion conditions of these two supraglottic airway devices and as conduits for endotracheal tube (ETT) insertion in adult patients undergoing elective surgeries.&#x0D; METHODS&#x0D; 100 patients belonging to American Society of Anaesthesiologists (ASA) grade 1 and 2 between 18 to 70 years were randomly divided into 2 groups of 50 each. In group A, Air-Q was used and in group B, I-gel. The following parameters were compared while inserting SAD and endotracheal tube (ETT): number of insertion attempts, insertion time, ease of insertion, intraoperative and postoperative complications.&#x0D; RESULTS&#x0D; Insertion in first attempt was 90 % in air- Q and 72 % in I-gel. The mean time of insertion for air-Q was 7.28  1.46 seconds which  was shorter as compared to I-gel which was 8.46  2.18 seconds (p = 0.002). Air Q was easy to insert in 93 % cases and I-Gel in 52 % cases. ETT insertion through Air-Q was easy when compared to I-Gel .Complications occurred in some patients in both the groups.&#x0D; CONCLUSIONS&#x0D; We concluded that Air-Q has better efficacy than I-gel in terms of insertion conditions and as a conduit for endotracheal intubation.</jats:p

Comparison Of Two Total Intravenous Anaesthesia Techniques : Propofol-Ketamine vs Propofol-Fentanyl In Minor Surgeries On Quality Of Induction And Haemodynamic Changes During Induction

Introduction: T.I.V.A has many advantages over inhalational anaesthetics . The drugs used for T.I.VA. have a quicker onset, recovery and minimal side effects .This study was conducted to compare the two T.I.V.A techniques Propofol-Ketamine and Propofol-Fentanyl during induction and to study their haemodynamic characteristics during induction.Materials and Methods: 100 patients undergoing short surgical procedures less than 30 minutes, of ASA grade I and II, 20 to 50 years of age were randomized into two groups. Group A – Patients received Injection ketamine 0.5 mg/kg I/V followed by I/V propofol 1% at the rate of 40mg/10seconds till the end point of induction. Group B -Patients received Injection fentanyl 1.5 microgram/kg I/V followed by I/V propofol 1% . Top up doses (25 mg) of propofol were given when the patient became light. Induction characteristics were studied and monitoring for HR, SBP, DBP, RR at 1 and 3 minutes of induction were done. The results were tabulated and analyzed statistically with student unpaired ‘t’test and Chi square test. P value(&lt;0.05) was considered significant.Results: Propofol- ketamine group is better as compared to propofol- fentanyl in T.I.V.A as lesser induction dose (85.00±7.04 mg) and less top up doses of propofol were required (3.06±0.82) With lesser pain on induction and lesser involuntary movements. Propofol- ketamine group is better in terms of haemodynamic stability and also causes lesser depression of respiration.Conclusions: Propofol-Ketamine group is better during induction and produces stable haemodynamics compared to Propofol- Fentanyl group
