Endoscopic submucosal dissection (ESD) has enabled the collective resection and increased the accuracy of pathological diagnosis. However, ESD requires a long operation time, which results in increased doses of analgesics/sedatives, and causes worsening of respiratory and hemodynamic statuses. To reduce postoperative complications, we have applied ESD with CO(2) insufflation and general anesthe...

BACKGROUND The extent to which insufflation of oxygen into the posterior pharynx during laryngoscopy prolongs adequate saturation in infants and small children remains unknown. Therefore, we compared oxygen saturation over time in preoxygenated small children with and without posterior pharynx oxygen insufflation. METHODS After induction of anesthesia with sevoflurane and propofol, infants an...

BACKGROUND Endoscopic parathyroidectomy and thyroidectomy were introduced into clinical practice in 1995. Concerns about the use of carbon dioxide insufflation in the neck exist owing to reports of potential adverse metabolic and hemodynamic changes. HYPOTHESIS Carbon dioxide insufflation in the neck may cause adverse effects on hemodynamic and blood gas levels. These adverse effects may refl...

The valveless trocar system is a novel insufflator that circulates carbon dioxide in the abdominal cavity. Herein, we report an infant with severe hypothermia due to use of this insufflator. An 83-day-old infant (body weight 3862 g) with gastroesophageal reflux underwent laparoscopic Nissen fundoplication. After insufflation was initiated, his body temperature acutely dropped to 34.4 °C. Standa...

Adults and children with neuromuscular disease exhibit weak cough and are susceptible to recurrent chest infections, a major cause of morbidity and mortality. Mechanical insufflation/exsufflation may improve cough efficacy by increasing peak cough flow. It was hypothesised that mechanical insufflation/exsufflation would produce a greater increase in peak cough flow than other modes of cough aug...

During surgical laparoscopy, total hepatic blood flow (THBF) may be modified by CO2insufflation, changes of tilt, ventilation with high tidal volume, hypercapnia, and anesthesia, but little information is available on the THBF during the procedure. To investigate the changes of hepatic blood flow following the combination of abdominal CO2 insufflation and changes of tilt, we measured mean arter...

BACKGROUND Supraglottic airway devices (SADs) play an increasing role in airway management in clinical anaesthesia and emergency medicine. Until now, no data exist concerning the extent of oesophageal insufflation when oropharyngeal leak pressures are exceeded. METHODS Laryngeal masks LMA-Supreme™ and LMA-ProSeal™, laryngeal tubes LTS-D and LTS II, Combitube™, and I-Gel were inserted into unf...

OBJECTIVE To evaluate the efficacy of combined infiltrative bupivacaine with low intraperitoneal pressure insufflation in reducing the post-laparoscopic pain in patients undergoing laparoscopic cholecystectomy (LC). METHODS This randomized prospective single-blind study included 473 patients undergoing LC. The study took place at University Hospital Center Mother Teresa, Tirana, Albania betw...
