Résumé
Mucormycosis is a fatal opportunistic fungal infection that typically occurs in immunocompromised patients. The classical manifestation of mucormycosis is a rhinocerebral infection, and although primary gastrointestinal infection is uncommon, it has an extremely high mortality rate in immunocompromised patients. Furthermore, cases of gastrointestinal mucormycosis in an immunocompetent host are rarely reported. Here, we describe our experience of a male patient, with no underlying disease, who succumbed to a bowel infarction caused by intestinal mucormycosis during mechanical ventilatory care for severe pneumonia and septic shock.

BACKGROUND: It is well known that intravenous patient controlled analgesia (IV-PCA) is an effective method to reduce the magnitude of postoperative pain. However, we do not know the appropriate time to start the IV-PCA. To determine the appropriate time to minimalize the sympathetic stimulation and shorten the awakening time after general anesthesia, experiments to indicate whether starting an infusion of the IV-PCA before the end of an operation has a minimal hemodynamic change and similar recovery index compared with the control group were done. METHODS: Seventy-eight patients scheduled for a total abdominal hysterectomy were randomly allocated to two groups. In the IV-PCA group (n = 37), we started the infusion of the IV-PCA before the end of the operation and in the control group (n = 41) which received no IV-PCA, we did not use the IV-PCA as a postoperative pain control method. We measured heart rate, blood pressure, postanesthesia recovery score every 10 minutes for 60 minutes and awakening time at the post-anesthesia care unit. RESULTS: The postanesthesia recovery scores on arrival, 10, 20, 30, 40 and 50 minute after arrival at the post-anesthesia care unit were lower in the IV-PCA group than in the control group. In addition the awakening time after vaporizer-off and at the post-anesthesia care unit was longer in the IV-PCA group than in the control group. CONCLUSIONS: We conclude that starting the infusion of the IV-PCA before the end of the operation is not effective in early recovery and awakening.

A number of complications during the use of double-lumen endobronchial tubes are reported, specifically tracheobronchial rupture, a rare but serious complication. Risk factors associated with tracheobronchial rupture include inexperienced endoscopists, intubating stylets, multiple vigorous attempts at intubation, overdistension of the tracheal or bronchial cuff with high pressure, position change with an inflated cuff, and anatomical abnormality. We report 2 cases of tracheobronchial rupture which occurred during the use of double-lumen endobronchial tubes.

BACKGROUND: Tracheal intubation can cause sympathetic stimulation such as hypertension and tachycardia. Many drug are used for reducing the incidence of hypertension and tachycardia induced by intubation. Among these drugs, fentanyl can be used with good result. The purpose of this study was to find the appropriate fentanyl injection time before intubation when a small dose (3 microgram/kg) was used. METHODS: We studied 82 ASA class 1 2 patients, scheduled for gynecological elective surgery, randomized into 5 groups. Group 1 received no fentanyl before intubation, and groups 2, 3, 4 and 5 received 3 microgram/kg fentanyl at 7 min, 5 min, 3 min and 1 min before intubation, respectively. The blood pressure and heart rate were checked at preinduction and post-intubation periods for 5 minutes. RESULTS: The increase of the heart rate was significantly lower in groups 2 and 3 than in group 5 just after intubation. Furthermore the increase of the mean blood pressure was significantly lower in groups 2, 3 and 4 than in group 5 just after intubation. The incidence of tachycardia and hypertension was significantly lower in groups 2, 3 and 4 than in group 5 just after intubation. CONCLUSIONS: When a small dose of fentanyl was used to blunt the intubation induced sympathetic stimulation, the appropriate time was prior to 3 minutes before intubation.
