Sonographic visualization and cannulation of the axillary vein in two arm positions during mechanical ventilation: A randomized trial.

Background: Abduction of the arm has been used for ultrasound-guided infraclavicular axillary vein cannulation. We evaluated the influence of arm position on sonographic visualization and cannulation of the axillary vein in patients receiving mechanical ventilation.

Methods: Sixty patients scheduled to undergo surgery under general anaesthesia with controlled mechanical ventilation were included in this prospective randomized study.

Arm position and collapsibility of infraclavicular axillary vein during voluntary breathing: An ultrasound-guided observational study.

Background: Arm abduction influences cross-sectional area of the infraclavicular axillary vein, yet the effect of arm abduction on collapsibility of the vein has not been quantified. Decrease in collapsibility of the axillary vein can enable successful cannulation and can decrease injury to underlying vital structures.

Methods: The infraclavicular axillary vein was scanned in 70 patients close to the clavicle with a high-frequency linear transducer in arm adducted position (Point A), after arm abduction at the initial probe position (Point A') and after tracing the vein medially close to clavicle (Point B).

Subarachnoid block with continuous TAP catheter analgesia produces less chronic pain and better functional outcome after inguinal hernioplasty: a randomized controlled observer-blinded study.

Background And Objectives: The major concern after inguinal hernioplasty is chronic postsurgical pain and impaired quality of life due to central sensitization. Preoperative, intraoperative, and postoperative pre-emptive analgesia using regional techniques may help prevent the development of central sensitization. This study evaluated the effect of regional anesthesia followed by continuous regional analgesia on postoperative pain and functional outcome following inguinal hernioplasty.

Congenital bronchoesophageal fistula in an adult-report of a rare case.

Congenital bronchoesophageal fistula (CBEF) is a rare entity in adults. Patients with CBEF present with cough and recurrent respiratory tract infection. Diagnosis is confirmed by barium esophagogram and contrast-enhanced computed tomography.

Estimation of effect-site concentration of propofol for laryngeal mask airway insertion using fentanyl or morphine as adjuvant.

Background And Aims: Insertion of laryngeal mask airway (LMA) requires adequate depth of anaesthesia, which provides jaw relaxation and suppression of upper airway reflexes. Propofol can provide these conditions especially when combined with narcotics. This study had been designed to find out the effect-site concentration (EC50) of propofol using target controlled infusion (TCI) when fentanyl or morphine is added as an adjuvant.

A comparative study between Truview(PCD) laryngoscope and Macintosh laryngoscope in viewing glottic opening and ease of intubation: A crossover study.

Background: Truview(PCD) laryngoscope is specially designed to aid positioning of the endotracheal tube as well as to record entry of the tube into glottis. Aim of the study is to compare the view of glottic opening and ease of intubation between Truview(PCD) laryngoscope and Macintosh laryngoscope in patients undergoing general anesthesia (GA).

Methodology: Two hundred patients undergoing elective surgery, under GA were randomized into two groups, Group TV and Group ML.

Effect of positioning from supine and left lateral positions to left lateral tilt on maternal blood flow velocities and waveforms in full-term parturients.

Positioning the parturient from supine to the left lateral tilt position (supine-to-tilt) may not effectively displace the gravid uterus, but turning from the left lateral position to the left lateral tilt position (left lateral-to-tilt) may keep the gravid uterus displaced and prevent aortocaval compression. Fifty-one full-term parturients were randomly placed in the left lateral position, supine-to-tilt and left lateral-to-tilt positions using a Crawford wedge. Femoral vein area, femoral vein velocity, femoral artery area, pulsatility index, resistance index and right arm mean arterial blood pressure and heart rate were recorded.
