Effects of pneumoperitoneum on severe hypernatremia in an adult patient who underwent laparoscopic surgery of hydatid cysts.

We describe the first case of severe hypernatremia associated to laparoscopic surgery for hydatid cyst in an adult patient after the use of hypertonic saline solution with complete resolution. Severe hypernatremia is an unusual fact at the immediate postoperative period but may have fatal consequences for the patient and need immediate action. The patient reached a serum sodium concentration of 179 mmol/L without adverse effects after 6 days of treatment.

Randomized double-blind comparison of remifentanil and alfentanil in patients undergoing laparoscopic cholecystectomy using total intravenous anesthesia.

Background And Aims: To compare the use of remifentanil and alfentanil to suppress intraoperative adrenergic response of pain and the influence of these drugs on the recovery profile in patients undergoing laparoscopic cholecystectomy using a total intravenous anesthesia (TIVA) technique.

Material And Methods: One hundred patients undergoing elective laparoscopic cholecystectomy were randomized to be managed with either remifentanil (group R) or alfentanil (group A). During general anesthesia, we evaluated adrenergic responses to intubation to first surgical incision and over the surgical procedure.

Role of laryngeal mask airway in laparoscopic cholecystectomy.

Laparoscopic cholecystectomy is one of the most commonly performed surgical procedures and the laryngeal mask airway (LMA) is the most common supraglottic airway device used by the anesthesiologists to manage airway during general anesthesia. Use of LMA has some advantages when compared to endotracheal intubation, such as quick and ease of placement, a lesser requirement for neuromuscular blockade and a lower incidence of postoperative morbididy. However, the use of the LMA in laparoscopy is controversial, based on a concern about increased risk of regurgitation and pulmonary aspiration.

Robust and sustained effect of ketamine infusions coadministered with conventional antidepressants in a patient with refractory major depression.

Antidepressant treatments show low capacity to achieve full clinical remissions. Electroconvulsive therapy is an alternative treatment which has been shown to be more effective but it is not well tolerated and there are concerns regarding its safety. We present the case of a patient with resistant depression and modest and transient response to ECT and who showed a robust and maintained response after six i.

Laryngeal mask, laryngeal tube, and Frova introducer in simulated difficult airway.

Background: The use of supraglottic devices is rising in the prehospital management of difficult airway; moreover, we think that patients with multiple trauma or cervical instability can take advantage of these devices without opening or retiring the cervical collar.

Objective: To compare speed and ease of use between Laryngeal Tube S (LTS) and the Ambu AuraOnce laryngeal mask (LMA).Our second objective was to evaluate changing these devices to an endotracheal tube (ETT) using a Frova introducer.

Comparison of Laryngeal Mask Airway Supreme and Laryngeal Mask Airway Proseal with respect to oropharyngeal leak pressure during laparoscopic cholecystectomy: a randomised controlled trial.

Context: A comparison of the efficacy and safety of the Laryngeal Mask Airway (LMA) Supreme (LMAS) versus the LMA Proseal (LMAP) in elective laparoscopic cholecystectomy.

Objectives: To compare the LMAS with LMAP in terms of ventilatory efficacy, airway leak pressure (airway protection), ease-of-use and complications.

Design: Prospective, single-blind, randomised, controlled study.

The Laryngeal Mask Airway Supreme for positive pressure ventilation during laparoscopic cholecystectomy.

Study Objective: To evaluate the Laryngeal Mask Airway Supreme (SLMA) in patients undergoing laparoscopic cholecystectomy.

Design: Prospective observational study.

Setting: University-affiliated hospital.
