Comparison of hemodynamic responses to nasal intubation in cancer patients receiving opioid-free general anesthesia versus standard regimen.

Background And Aims: Nasotracheal intubation evokes greater hemodynamic responses than oral intubation. We compared the heart rate (HR) and mean arterial pressure (MAP) responses following nasal intubation during opioid-free anesthesia (OFA) using intravenous lignocaine versus standard regimen using morphine in cancer patients undergoing tumor resection.

Material And Methods: This randomized, double-blinded study was conducted in 84 adults.

Comparison of intraoperative blood pressure values measured by noninvasive versus invasive methods during normotension, hypertension, and hypotension.

Background And Aims: Monitoring of intraoperative blood pressure (BP) is essential. We aimed to compare BP values simultaneously recorded by invasive and noninvasive methods under general anesthesia (GA) during normotension, hypertension, and hypotension. Mean arterial pressure (MAP) values calculated by the automated technique were also compared to the values obtained using predefined formula.

Usefulness of ultrasound in confirming the correct placement of Ryle's tube compared to the traditional method of auscultation in normal versus overweight and obese patients.

Background And Aims: Auscultation to verify Ryle's tube position is difficult in obese patients. We compared the usefulness of ultrasonography (USG) versus auscultation in confirming the correct Ryle's tube placement in normal versus overweight or obese patients, time taken for confirmation, and incidence of reinsertion.

Material And Methods: A prospective, observational study was carried out on 80 patients.

Effects of oral melatonin premedication on hemodynamic responses to intubation, anesthetic requirements and postoperative sedation: A randomized trial.

Background And Aims: Sedative effects of melatonin may have an additive effect on general anesthesia (GA). We compared hemodynamic response to intubation following oral premedication with melatonin versus placebo. Induction dose of propofol, isoflurane and fentanyl consumption were also compared.

Usefulness of bougie-preloaded proseal laryngeal mask airway versus digital insertion technique in correct placement of the device.

Background And Aims: Digital technique of proseal laryngeal mask airway (PLMA) insertion carries high chance of failed first attempt successful placement. We aimed to compare the number of attempts taken for correct placement of bougie-preloaded PLMA versus traditional digital insertion technique. Ease of insertion, time taken, hemodynamic responses during insertion, and evidence of trauma were also assessed.

Effects of bilateral transmucosal sphenopalatine ganglion block on intraoperative anesthetic requirements and recovery profile in children undergoing palatoplasty under general anesthesia.

Background And Aims: Sphenopalatine ganglion block (SPGB) given as injection provides excellent perioperative analgesia during palatoplasty. Our objectives were to assess the effect of transmucosal SPGB on anesthetic requirements, intraoperative hemodynamics, recovery time, and emergence delirium in children undergoing palatoplasty.

Material And Methods: This prospective, randomized study was conducted in 30 children with cleft palate undergoing palatoplasty, divided into two equal groups.

Comparison of aerosol box intubation with styletted endotracheal tube and intubation over bougie: A randomized controlled trial.

Background And Aims: Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) is an infectious disease. The use of video laryngoscopes is recommended for intubation of patients with COVID-19. But in resource-poor countries, it is rare to have video laryngoscopes available.

Safety and ease of awake fiberoptic intubation with use of oxygen insufflation versus suction to clear secretions during procedure.

Background And Aims: During awake fiberoptic intubation (AFOI), clearing secretions is usually done by suctioning. The study objectives were to assess the safety of AFOI with the use of oxygen insufflation versus suction to clear secretions from the field of vision during the procedure as assessed by incidence of desaturation <95%, ease of intubation, and time taken to secure the airway.

Material And Methods: This prospective randomized study was conducted in 40 adult patients with difficult airways requiring AFOI.

Incidence and Severity of Postoperative Complications in Patients Undergoing Surgery Following COVID-19 Infection at a Tertiary Care Center in South India.

Background: The occurrence of postoperative pulmonary complications (PPCs) and other sequelae of COVID-19 infections like thromboembolic events in patients coming for surgery following COVID-19 infection in the Indian population had not been adequately studied.

Aim Of The Study: We evaluated the incidence of PPCs, acute kidney injury, and thromboembolic complications such as pulmonary embolism, deep-vein thrombosis, myocardial infarction, stroke, and 30-day mortality rate in post-COVID-19 patients undergoing surgery compared to those without a history of COVID-19 infection.

Settings And Design: It was a retrospective, observational, case-control study conducted in a tertiary care center.

Comparison of arterial to end-tidal carbon dioxide gradient P (a-ET)CO in volume versus pressure controlled ventilation in patients undergoing robotic abdominal surgery in the Trendelenburg position. A randomised controlled study.

Background And Aims: Robotic surgery is increasingly prevalent as an advancement in care. Steep head-down positions in pelvic surgery can increase the ventilation-perfusion mismatch and increase ventilatory requirements to offset carbon dioxide (CO) increases consequent to pneumoperitoneum. The primary objective was to assess the impact of two ventilatory strategies, volume versus pressure-controlled ventilation on the arterial to end-tidal carbon dioxide gradient P (a-ET)CO in patients undergoing robotic surgery in the Trendelenburg position.
