Current Ventilator and Oxygen Management during General Anesthesia: A Multicenter, Cross-sectional Observational Study.

Background: Intraoperative oxygen management is poorly understood. It was hypothesized that potentially preventable hyperoxemia and substantial oxygen exposure would be common during general anesthesia.

Methods: A multicenter, cross-sectional study was conducted to describe current ventilator management, particularly oxygen management, during general anesthesia in Japan.

[The postoperative management of patients after pluropneumonectomy--influence of the mode of the operation].

Background: In our hospital, a new mode of operation was introduced in pleuropneumonectomy from 2004. We studied how these changes had affected postoperative management of patients after pleuropneumonectomy.

Methods: We retrospectively reviewed 22 patients who had undergone pleuropneumonectomy for malignant pleural mesothelioma from 2001 to 2008.

[Anesthetic management of patients 100 years of age and above undergoing emergency abdominal surgery].

We anesthetized four patients aged 100 years and above who underwent emergency abdominal surgery. Case 1 : A 100-year-old woman with ileus caused by rectal cancer had chronic heart failure in whom colostomy was performed. Case 2 : A 101-year-old man with incarceration of inguinal hernia and history of cerebral infarction.

[A case of general anesthesia combined with epidural anesthesia in a pregnant woman undergoing laparoscopic cholecystectomy].

We report a case of general anesthesia for laparoscopic cholecystectomy at 12 weeks of gestation. A 20-year-old woman weighing 123 kg was admitted with epigastralgia. She was diagnosed as pregnancy of 6 weeks of gestation and acute cholecystitis.

[Combined paravertebral lumbar plexus and parasacral sciatic nerve block for reduction of hip fracture in four patients with severe heart failure].

We experienced four cases of anesthesia for hip fracture reduction in patients with severe heart failure, where anesthesia was attempted with combined paravertebral lumbar plexus and parasacral sciatic nerve block instead of spinal anesthesia. The anesthesia was successful without any sequelae. The patients' characteristics are as follows.
