Randomized Controlled Trial Clinical TrialEfficacy of pre-incisional bupivacaine infiltration on postoperative pain relief after appendectomy: prospective double-blind randomized trial.
Pain is the most undesirable and threatening experience for surgical patients. This study aims to determine the efficacy of pre-incisional analgesic bupivacaine infiltration (preemptive analgesia) on postoperative pain relief after appendectomy. A prospective randomized double-blinded study was conducted on 123 patients aged 13-45 years with a preoperative and-postoperative diagnosis of acute appendicitis admitted to Siriraj Hospital, Bangkok, from January to May 2002. ⋯ So were the total number of morphine injections and the amount of morphine used postoperatively. The pain reduction could be due to interruption of inflammatory or pain mediator cascades that normally occur during an operation. This study showed that pre-incisional bupivacaine infiltration is an effective and simple method of reducing postoperative pain for patients undergoing appendectomy.

Stab wounds are the main type of penetrating cardiac injury in China and they have a fairly good prognosis when the patient receives expeditious and appropriate management. The objective of this study is to present the experience of managing the patients with penetrating cardiac injuries. A retrospective study involving 82 cases with penetrating wounds of the heart in the past 16 years was carried out. ⋯ One patient died of exsanguination due to injury of multiple chambers; of the remaining 2 deaths after operation 1 was associated with abdominal injuries and the other with failure of cerebral resuscitation. From the experience reported in this study, early establishment of diagnosis and prompt thoracotomy against time are the fundamental factors affecting the outcome of penetrating cardiac injuries. Preoperative massive transfusion and pericardiocentesis are not advocated.

Risk factors for postoperative delirium after liver resection for hepatocellular carcinoma.
We investigated risk factors for delirium in 100 patients who underwent liver resection for hepatocellular carcinoma. Postoperative delirium developed in 17 (17%). ⋯ The percentages of patients with high aspartate and alanine aminotransferase activities, a high indocyanine green retention rate at 15 minutes, a low platelet count, and advanced cancer stage (II-IV) were higher in patients with a low (< 3.8 g/dl), rather than high (= 3.8 g/dl) serum albumin concentration. These findings indicate that multiple factors, including advanced age, impaired liver function, and advanced cancer stage, affect the development of postoperative delirium after liver resection for hepatocellular carcinoma.

Patterns and clinical outcomes associated with routine intravenous sodium and fluid administration after colorectal resection.
Excess intravenous water and sodium may be associated with postoperative complications and an adverse outcome. However, the effect of the magnitude of the surgery on such a relation has not been studied. This study assesses current practice in intravenous fluid and sodium administration after colonic and rectal resection and its relation to the postoperative outcome. ⋯ Current postoperative intravenous fluid prescription delivers approximately 2 liters of fluid and 140 mmol of sodium per day. Complications after colonic, but not rectal, resection are associated with more early postoperative daily intravenous sodium administration. Because colonic resection poses less of a physiologic insult than rectal resection, the overall outcome in the former group may be more sensitive to the interplay between fluid and sodium overload and patient co-morbidity.
