Endotracheal intubation in patients undergoing general anesthesia often causes hypertension and tachycardia, which may be altered when the efferent sympathetic fiber to the cardiovascular system is interrupted. The aim of the current study was to investigate the effects of different levels of spinal cord injury on the cardiovascular responses to intubation. Twenty patients without spinal injury served as controls. Arterial pressure, heart rate, and rhythm were recorded at intervals for up to 5 min after intubation. Plasma concentrations of catecholamines were also measured.

Background: Choice of premedication and hemodynamic stability are always remain important concerns during laryngoscopy and endotracheal intubation for Anesthesiologists. Dexmedetomidine offers anxiolytic, sedation, hypnosis, analgesia, antisialagogue action as well as sympatholysis which make most suitable drug as premedication. In both groups study solutions administered over 10 minutes. Both the groups were administered standard general anaesthesia and requirement of Propofol was noted as an induction agent. Heart rate, blood pressure systolic, diastolic and mean arterial pressure were compared at baseline, 2 min, 5 min, 10 minutes SD2, SD5, SD10 after study drugs administration, before induction BI , after induction AI , 1 minute T1 , 2 minutes T2 , 5 minutes T5 and 10 minutes T10 after laryngoscopy and intubation in both groups.

Volume 2, Number 1, February , pages Background: We compared the efficacy of intravenous fentanyl, esmolol and lidocaine in preventing hemodynamic response to laryngoscopy, endotracheal intubation and extubation in abdominal surgeries. Heart rate, systolic arterial pressure and diastolic arterial pressure were recorded before anesthesia induction and at laryngoscopy, at 1st, 3rd ,5th and 10th minutes of intubation, and then at the end of surgery before extubation, and at 1st, 3rd, 5th, and 10th minutes following extubation. Amounts of the administered drugs and side effects were recorded.

Background and Aims: Laryngoscopic manipulation and endotracheal intubation are noxious stimuli capable of producing tachycardia, arrhythmias and hypertension. The aim of this study was to arrive at an optimal dose of dexmedetomidine by comparing two doses with placebo to attenuate stress response during laryngoscopy and endotracheal intubation. Methods: It was a randomised, prospective, double-blind placebo-controlled study. After Institutional Ethical Committee clearance, ninety patients of American Society of Anesthesiologists Physical Status 1 were enrolled in the study and divided into three equal groups.

Background: Sympathetic response associated with laryngoscopy and endotracheal intubation is a potential cause for a number of complications especially in patients with cardio-vascular compromise.

Background: Laryngoscopy and tracheal Intubation are invariably associated with certain stress responses due to the sympatho-adrenal stimulation. These cardiovascular and neurohumoral alterations may directly affect the physiology and increase the risk. So far, various drugs have been tried but none has been considered ideal for blunting this presser response. Methods: Fifty patients, aged 15—50 years, scheduled for elective surgery under general anaesthesia, were randomly assigned to one of the two groups of 25 each, Group A magnesium group and Group B nitroglycerine group. Study drug was given seconds before tracheal intubation. Heart rate, Systolic blood pressure and Rate pressure product were recorded at different intervals after administering the study drug till 3 minutes after intubation.

Background: Laryngoscopy and tracheal intubation after the induction of anesthesia are nearly always associated with a sympathetic hyperactivity.
