A Comparative Study of Intubating Condition and Hemodynamic Responses Using Propofol or Thiopentone without Muscle Relaxants
Journal Title: Indian Journal of Anesthesia and Analgesia - Year 2019, Vol 6, Issue 4
Abstract
Introduction: Muscle relaxants are frequently used to facilitate endotracheal intubation during the induction of anesthesia. However, the administration of short-acting depolarizing muscle relaxants is associated with postoperative myalgias, malignant hyperthermia, hyperkalemia and increased intracranial or intraocular pressure. Aim: To compare the intubating condition and haemodynamic response to induction, laryngoscopy and intubation in patients induced with lignocaine, fentanyl and propofol or lignocaine, fentanyl and thiopentone and intubated without muscle relaxants. Methods: 40 patients were randomly allotted in P group [Propofol group] and T group [Thiopentone group]. Patients with the predicted difficulty of intubation, history of hypertension, history of asthma, drug or alcohol abuse, significant cerebrovascular disease and cardiovascular disease, BMI more than 30 kgm-2 were excluded from the study. The results were compared between both the groups. Jaw relaxation, vocal cord position, patient’s response to laryngoscopy and intubation were assessed and graded as excellent, good, and poor. Results: In this study higher incidence of ideal and acceptable intubating conditions were observed in 95% of patients in P group when compared with T group in which the acceptable intubating conditions were observed in 30% of the patients which is statistically significant (p < 0.05). The mean heart rate was decreased in both the groups after induction, but immediately after intubation, mean heart rate was high in group T, when compared with group P. Conclusion: We conclude that induction with Propofol, Fentanyl and Lignocaine provides better intubating conditions with less haemodynamic response to laryngoscopy and intubation than induction with Thiopentone, Fentanyl and Lignocaine.

To Compare the Efficacy of Intrathecal Buprenorphine and Midazolam Added as an Adjuvant to 0.5% Bupivacaine (Heavy) in Lower Abdominal Surgeries
Background: Opioid like Buprenorphine has been widely used as adjuvant intrathecally for providing prolonged post operative pain relief. Their advantages of neuraxial narcotics over systemic narcotics are well establishe...
To Compare The Haemodynamic Resopnses and Adequacy of Ventilation Between Laryngoscopic Endotracheal Intubation and Laryngeal Mask Airway Classic Insertion in Short Surgical Procedures Under General Anaesthesia with Muscle Relaxation
The haemodynamic response associated with laryngoscopy and tracheal intubation may be harmful to certain patients. The laryngeal mask airway (LMA) avoids the need for laryngoscopy and allows positive pressure ventilation...
