Randomized Controlled TrialThe effect of oral and IV ramosetron on postoperative nausea and vomiting in patients undergoing gynecological laparoscopy with total intravenous anesthesia.
Ramosetron can be administered orally as well as intravenously. We investigated the effect of oral ramosetron on postoperative nausea and vomiting (PONV) in patients undergoing gynecological laparoscopy. ⋯ The effect of oral ramosetron 0.1 mg was comparable to that of IV ramosetron 0.3 mg on the prevention of PONV in women undergoing gynecological laparoscopy with TIVA. Both the oral and IV forms were effective at preventing PONV during the first 1 h after surgery.

Randomized Controlled Trial Comparative StudyHyperventilation versus standard ventilation for infants in postoperative care for congenital heart defects with pulmonary hypertension.
In infants undergoing surgery for cardiac defects with left-to-right shunt, a hyperventilation strategy has been applied to prevent pulmonary hypertensive crisis (PHC). Hyperventilation with a large tidal volume and/or higher airway pressure, however, may be detrimental to the lung. This randomized study compared the effects of hyperventilation versus standard ventilation. ⋯ Hyperventilation may cause lung injury and systemic inflammation in infants with pulmonary hypertension undergoing corrective heart surgery.

Randomized Controlled TrialEffect of different anesthetic agents on oculocardiac reflex in pediatric strabismus surgery.
The oculocardiac reflex (OCR) occurs frequently during pediatric strabismus surgery. The aim of this study was to assess the effects of various anesthetic regimens on the incidence of OCR during the surgery. ⋯ Propofol or remifentanil anesthesia was associated with a higher incidence of OCR during pediatric strabismus surgery than sevoflurane and desflurane anesthesia, when either ketamine or midazolam was used as an induction agent.

Randomized Controlled TrialPreoperative fluid and electrolyte management with oral rehydration therapy.
We hypothesized that oral rehydration therapy using an oral rehydration solution may be effective for preoperative fluid and electrolyte management in surgical patients before the induction of general anesthesia, and we investigated the safety and effectiveness of oral rehydration therapy as compared with intravenous therapy. ⋯ The results suggest that the oral rehydration therapy with an oral rehydration solution before surgery is superior to the current preoperative intravenous therapy for the provision of water, electrolytes, and carbohydrates, and this therapy should be considered as an alternative to the intravenous therapy for preoperative fluid and electrolyte management in selected surgical patients in whom there is no reason to suspect delayed gastric emptying.

Case Reports Comparative StudyPentax-AWS airway Scope as an alternative for awake flexible fiberoptic intubation of a morbidly obese patient in the semi-sitting position.
For anesthesia induction in a morbidly obese patient with a full stomach, awake flexible fiberoptic bronchoscope (FOB) intubation in the semi-sitting position may be a suitable choice. A new rigid indirect videolaryngoscope, the Pentax-AWS system, has a unique feature of an adjustable built-in monitor and is designed to be used in patients in various positions. However, the efficacy of its use in such situations has not been investigated or reported. ⋯ The patient's trachea was intubated with the Pentax-AWS by an anesthesiologist positioned at the patient's right and facing her. The Pentax-AWS offered easy intubation under good visualization of the glottic aperture as a consequence of its adjustable integrated monitor, in contrast to difficult intubation with other videolaryngoscopes which require an external monitor. This report illustrates that the Pentax-AWS is useful as an alternative for flexible fiberoptic intubation under these circumstances, as a consequence of its adjustable built-in monitor and integrated tube channel.
