Surgical repair of Ebstein's anomaly.

Ebstein's anomaly is a complex malformation that has been treated by various surgical techniques, with variable results. We have developed a repair-by plication of the free wall of the atrialized portion of the right ventricle, posterior tricuspid annuloplasty, and right atrial reduction--that has been used since 1972 in 16 patients. The repair is based on the construction of a monocusp valve by the use of the anterior leaflet of the tricuspid valve, which is usually enlarged in this anomaly. There were 14 operative survivors and no instances of complete heart block. Two patients with refractory dysrhythmias due to the Wolff-Parkinson-White syndrome underwent successful intraoperative epicardial and endocardial mapping and surgical division of accessory pathways. This repair has resulted in improvement in the operative mortality and in gratifying early and late results in most patients.     

Ultrasound-guided bilateral rectus sheath block vs. conventional local analgesia in single port laparoscopic appendectomy for children with nonperforated appendicitis

Introduction

Despite its minimally invasive approach, laparoscopic surgery can cause considerable pain. Regional analgesic techniques such as the rectus sheath block (RSB) offer improved pain management following elective umbilical hernia repair in the pediatric population. This effect has not been examined in laparoscopic single-incision surgery in children. We sought to compare the efficacy of bilateral ultrasound-guided RSB versus local anesthetic infiltration (LAI) in providing postoperative pain relief in pediatric single-incision transumbilical laparoscopic assisted appendectomy (TULA) with same-day discharge.

Short women with severe sepsis-related acute lung injury receive lung protective ventilation less frequently: an observational cohort study

Introduction  

Lung protective ventilation (LPV) has been shown to improve survival and the duration of mechanical ventilation in acute lung injury (ALI) patients. Mortality of ALI may vary by gender, which could result from treatment variability. Whether gender is associated with the use of LPV is not known.
