A Prospective Crossover Study Evaluating the Efficacy of King Vision Video Laryngoscope in Patients Requiring General Anesthesia with Endotracheal Intubation.

Background: Direct laryngoscopy used for tracheal intubation requires aligning the pharyngeal, laryngeal and oral axes to achieve a line of sight. Video laryngoscopy provides a better view of the glottis without the need for aligning the three axes.

Aims: To evaluate the effectiveness of King vision laryngoscope over Macintosh laryngoscope in visualizing the glottis and intubating the trachea, when used on a same patient as in a cross over manner.

Effect of adding clonidine to intrathecal bupivacaine on the quality of subarachnoid block: A prospective randomized double-blind study.

Context: The purpose of adding an adjuvant to local anesthetic in a central neuraxial blockade is to augment the desirable pharmacological actions of the agent and/or to minimize its undesirable pharmacological effects. Clonidine is an alfa-2 receptor agonist which has gained popularity in recent times as an adjuvant in spinal anesthesia.

Aims: To evaluate the influence of clonidine on the hemodynamic stability and the duration of anesthesia when added to intrathecal hyperbaric bupivacaine.

Comparison of GlideScope video laryngoscope with Macintosh laryngoscope in adult patients undergoing elective surgical procedures.

Background: GlideScope (GS) is a video laryngoscope that allows a real-time view of the glottis and endotracheal intubation. It provides a better view of the larynx without the need for alignment of the airway axes.

Aim: This prospective randomized comparative study is designed to compare the intubation time, hemodynamic response, and complications associated with intubation using a GS or Macintosh laryngoscope (ML) in adult subjects undergoing elective surgical procedures.

Comparison of the ease of tracheal intubation by postgraduate residents of anesthesiology using Airtraq™ and Macintosh laryngoscopes: An observational study.

Context: Airtraq™ (Prodol Meditec, Vizcaya, Spain) is a recently developed laryngoscope, which facilitates easy visualization of glottis through a matrix of sequentially arranged lenses and mirrors. In this observatory study, we sought to compare the ease of tracheal intubation with Airtraq™ and Macintosh laryngoscope when performed by 2(nd) year postgraduate residents of Anesthesiology in NRI Medical College, Mangalagiri.

Aims: To compare the ease of tracheal intubation by Airtraq™ laryngoscope with that by Macintosh laryngoscope among the 2(nd) year postgraduate residents of anesthesiology in terms of time taken for intubation and the rise of rate-pressure product (RPP) with intubation.

Out of the blue! Thyroid crisis.

A 45-year-old male patient with an irregularly irregular rhythm and fast ventricular rate was posted for an emergency laparotomy for hollow viscus perforation. His history was not suggestive of any systemic disorders. An echocardiography revealed left ventricular dysfunction with an ejection fraction of 47% without any valvular or chamber abnormality.

Critical upper limb ischemia due to thrombus in the right subclavian artery: An uncommon complication of right internal jugular vein cannulation.

Internal jugular catheterization is associated with arterial puncture in 6.3-9.4% of cases and subclavian artery (SCA) injuries are probably under-reported.

Comparison of equipotent doses of rocuronium and vecuronium.

Background: Rocuronium (R) bromide and vecuronium (V) are monoquaternary aminosteroid compounds. The aim of this study was to evaluate the onset time, conditions of intubation and duration of action of equipotent doses (3ED95) of R and V.

Materials And Methods: The study was carried out in 60 adult American Society of Anesthesiologists physical status 1-2 patients of age 20-60 years.

Comparison of the efficacy of dexmedetomidine with that of esmolol in attenuating laryngoscopic and intubation response after rapid sequence induction.

Context: Laryngoscopy and tracheal intubation produce sympathetic overdrive by catecholamine release resulting in hypertension and tachycardia. Various agents are being tried to combat the intubation response over years.

Aims: This study is aimed at comparing dexmedetomidine which is a highly selective alpha-2 agonist with an ultra-short acting beta blocker, esmolol to see which among the two is better in attenuating the hemodynamic response to laryngoscopy and tracheal intubation.

Ischemic pain mandating unconventional position for epidural placement.

Positioning has always been a special and important concern for any regional anesthetic technique. The standard positions recommended for epidural anesthesia include lateral decubitus, sitting and prone. We report a special situation where we employed the standing position for placing epidural catheter.

Cramps and tingling: A diagnostic conundrum.

Tetany a syndrome of sharp flexion of the wrist and ankle joints (carpopedal spasm), muscle twitching, cramps and convulsions, sometimes with an attack of stridor, is due to hyperexcitability of nerves and muscles caused by decreased extracellular ionized calcium. Hyperventilation secondary to anxiety can result in tetany. We report a case of hyperventilation induced tetany 2 h following spinal anesthesia for inguinal hernia repair.
