RESUMO
Small gauze is used in laparoscopy; therefore, retention of gauze can occur. We experienced a case of retention of a radiopaque thread that ruptured from a piece of gauze and moved into the peritoneum during a scheduled laparoscopy. The patient was a 65-year-old woman who underwent laparoscopic-assisted transverse colon resection for transverse colon cancer. A commercial gauze commonly used for laparoscopy was used during the surgery. To more easily identify the gauze during surgery, radiopaque threads extending up to 3.0 cm from the two diagonal corners of the gauze body were attached. After wound closure, radiography showed a radiopaque thread-like substance in the abdomen. Minor laparotomy was performed, and part of the radiopaque thread was discovered. On postoperative day 22, the patient was in remission and discharged.
RESUMO
PURPOSE: We conducted a randomized, double-blinded study to test our hypothesis that caudal blockade as preemptive analgesia for low back surgery might accelerate time to walking exercise following surgery and reduce postoperative analgesics, thereby attaining faster recovery of cognitive function. METHODS: Our study included 51 elderly patients >70 years with American Society of Anesthesiologists (ASA) physical status 1-3, who underwent lumbosacral surgery under general anesthesia. After anesthetic induction and tracheal intubation, patients in the study group (group B) were injected with simple 0.5% bupivacaine [10 ml x height (m)] as a caudal block 15 min before surgical incision, whereas patients in the control group (group C) received normal saline. After surgery, patients had access to intravenous patient-administered analgesia (IV PCA), fentanyl, for postoperative pain relief. We assessed Mini-Mental State Examination (MMSE) scores before and after the surgery, values of visual analog scale (VAS) for postoperative analgesic status, fentanyl consumption during and for 3 days after surgery, and time to begin walking exercise after surgery. RESULTS: VAS value of group B patients was significantly lower than those in group C throughout the postoperative 48-h period (p < 0.005), and group B patients began walking exercise significantly earlier than those in group C [mean +/- standard deviation (SD) 70.2 (14.3) in group C, and 61.9 (7.6) in group B; p = 0.0133]. Cognitive function level was higher in group B than in group C patients 24 h after operation. CONCLUSIONS: Caudal blockade as preemptive analgesia shortened the time to start walking exercise after surgery and accelerated recovery of postoperative cognitive function.
