Comparative Evaluation of Nalbuphine and Fentanyl for Attenuation of Pressor Response to Laryngoscopy and Tracheal Intubation in Laparoscopic Cholecystectomy.

Background In this study, our primary aim was to compare the efficacy of fentanyl and nalbuphine in attenuating the pressor response to laryngoscopy and tracheal intubation in patients undergoing laparoscopic cholecystectomy under general anesthesia. The secondary aim was to observe hemodynamic response to pneumoperitoneum and to study the level of sedation using the Richmond Agitation-Sedation Scale (RASS). Methodology A total of 180 patients belonging to the American Society of Anesthesiologist Physical Status class I/II scheduled to undergo elective laparoscopic cholecystectomy under general anesthesia were divided into two groups of 90 each.

The effects of intravenous dexmedetomidine premedication on intraocular pressure and pressor response to laryngoscopy and intubation.

Background And Aims: Penetrating eye injuries are a challenge for the anesthesiologists in emergency due to increase in intraocular pressure (IOP). The aim of this study was to evaluate the effects of intravenous dexmedetomidine premedication on changes in IOP and hemodynamic response following laryngoscopy and tracheal intubation.

Material And Methods: Hundred patients aged 18-60 years undergoing elective nonophthalmic surgery were divided into two groups of 50 each.

Urinothorax: A rare cause of severe respiratory distress.

A case of massive right pleural effusion in a postoperative patient of percutaneous nephrolithotomy leading to severe respiratory distress is reported. A high degree of clinical suspicion and prompt intervention by insertion of an intercostal drainage tube prevented the patient from going in to respiratory failure. The development of arrhythmias confused the picture increasing the morbidity of the patient.

Tuberculosis and anaesthesia.

Anaesthesiologists and other healthcare workers have been at risk for nosocomial infection with tuberculosis for many years, however the advent of effective infection control techniques and the development of antibiotics for Mycobacterium tuberculosis have decreased the risk of nosocomial infection. The risk of transmission of tuberculosis from patients to healthcare workers is a neglected problem in many developing and underdeveloped countries as they lack the resources to prevent nosocomial transmission of tuberculosis. Patients with active tuberculosis can present with problems related to tuberculosis or unrelated problems like trauma to anaesthetist for various surgeries.

Prallethrin poisoning: A diagnostic dilemma.

Pyrethroid insecticides are very widely used in agriculture and household due to their high effectiveness and low toxicity in humans. Despite their extensive worldwide use, there are a few reports of human pyrethroid poisoning. The poisoning has a varied presentation and its symptoms overlap with those of other compounds, which can lead to misdiagnosis.

Fibreoptic bronchoscopy without sedation: Is transcricoid injection better than the "spray as you go" technique?

Aim: The aim of the study was to compare transcricoid injection with spray as you go technique for diagnostic fibreoptic bronchoscopy, to perform the procedure without sedation and to record any complication or side effects.

Methods: Sixty patients belonging to the age group 20-70 years, undergoing diagnostic bronchoscopy over a period of 6 months, were randomly selected and divided into two groups alternatively to receive 3 ml of 4% lignocaine by a single transcricoid puncture (group I) or 2 ml of 4% lignocaine instilled through the bronchoscope on to the vocal cords and further 1 ml of 2% lignocaine into each main bronchus (group II). Additional dose of lignocaine as required was given in both the groups.

Use of transcutaneous electrical nerve stimulation as an adjunctive to epidural analgesia in the management of acute thoracotomy pain.

The present randomized study was conducted in our institute of pulmonary medicine and tuberculosis over a period of 1 year. This study aimed to evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) as an adjunctive to thoracic epidural analgesia for the treatment of postoperative pain in patients who underwent posterolateral thoracotomy for decortication of lung. Sixty patients in the age group 15-40 years scheduled to undergo elective posterolateral thoracotomy were divided into two groups of 30 each.
