Comparative Study Controlled Clinical Trial
Gastric emptying of a carbohydrate-electrolyte solution in healthy volunteers depends on osmotically active particles.
Preoperative ingestion of only clear fluids until 2 hours before induction of anesthesia is a common preoperative fasting regimen. Gastric emptying times, however, vary among clear fluids. We therefore investigated the gastric emptying of 2 clear glucose-electrolyte drinks. ⋯ Gastric emptying is significantly faster for OS-1(®) than for Pocari Sweat(®).

Nicotine, which is found in tobacco, is one of the most toxic of all known poisons. A 31-year-old woman was brought to our emergency department 2 hours after ingesting a usually fatal dose of a tobacco extract. Although gastric lavage was once commonly used to treat poisoning cases of this type, lavage can lead to such complications as aspiration, hypoxia, oropharyngeal and gastric trauma, and electrolyte disturbances. ⋯ No changes were noted in the vital signs, and no obstruction of the airways was observed. The patient recovered quickly and was discharged the following day. Ultrathin esophagogastroduodenoscopy helped determine the diagnosis and ensure that gastric lavage had been performed without complications.

Cardiopulmonary resuscitation and mild therapeutic hypothermia (MTH) have improved neurological outcomes after sudden cardiac arrest, but the factors affecting favorable neurological outcome remain unclear. The aim of this study was to clarify these factors in patients in cardiac arrest treated with MTH. ⋯ MTH is associated with favorable neurological outcomes after sudden cardiac arrest, including those with non-shockable rhythms, especially in patients with prehospital ROSC.

Case Reports
Assessment of cerebral circulation in the acute phase of subarachnoid hemorrhage using perfusion computed tomography.
Primary brain damage, caused by acute ischemic changes during initial hemorrhage, is an important cause of death and disability following subarachnoid hemorrhage (SAH). However, the mechanism underlying the reduction in cerebral circulation in patients in the acute stage of SAH remains unclear. The goal of this study was to clarify this mechanism with the aid of perfusion computed tomography (CT). ⋯ Hemodynamic disturbances frequently occur after SAH. These abnormalities probably reflect the primary brain damage caused by initial hemorrhage. Perfusion CT is valuable for detecting hemodynamic changes in the acute stages of SAH.

In most cases of pancreatic head cancer, surgery often results in noncurative resection, which is frequently related to inadequate clearance of the mesopancreas. ⋯ Our method of LPA-PD helps secure the negative margin of the mesopancreas and enables complete circumferential lymphadenectomy around the SMA. Therefore, LPA-PD may increase the true curative resection rate and decrease the locoregional recurrence rate compared with standard PD.
