Randomized Controlled TrialPostoperative analgesic effect of preoperative intravenous flurbiprofen in arthroscopic rotator cuff repair.
This study was carried out to evaluate the postoperative analgesic effects of preoperative intravenous flurbiprofen in patients undergoing arthroscopic rotator cuff repair under general anesthesia. ⋯ These results show that preoperative intravenous flurbiprofen facilitates the analgesic effect in the early postoperative period after arthroscopic rotator cuff repair.

Randomized Controlled Trial Comparative StudyHyperventilation versus standard ventilation for infants in postoperative care for congenital heart defects with pulmonary hypertension.
In infants undergoing surgery for cardiac defects with left-to-right shunt, a hyperventilation strategy has been applied to prevent pulmonary hypertensive crisis (PHC). Hyperventilation with a large tidal volume and/or higher airway pressure, however, may be detrimental to the lung. This randomized study compared the effects of hyperventilation versus standard ventilation. ⋯ Hyperventilation may cause lung injury and systemic inflammation in infants with pulmonary hypertension undergoing corrective heart surgery.

Randomized Controlled TrialPerineural morphine in patients with chronic ischemic lower extremity pain: efficacy and long-term results.
To compare the efficacy, safety, and impact on daily activity of peripherally administered morphine plus a local anesthetic with that of a local anesthetic alone in patients with chronic ischemic lower extremity pain. ⋯ A peripherally administered bupivacaine plus morphine combination provided better and longer analgesia for ischemic pain compared to bupivacaine alone for the short term, but not for the long term. On the other hand, our results show that continuous popliteal treatment is an effective, safe, and comfortable modality for long-term use in the home setting for patients with intractable chronic pain.

Randomized Controlled TrialPreoperative fluid and electrolyte management with oral rehydration therapy.
We hypothesized that oral rehydration therapy using an oral rehydration solution may be effective for preoperative fluid and electrolyte management in surgical patients before the induction of general anesthesia, and we investigated the safety and effectiveness of oral rehydration therapy as compared with intravenous therapy. ⋯ The results suggest that the oral rehydration therapy with an oral rehydration solution before surgery is superior to the current preoperative intravenous therapy for the provision of water, electrolytes, and carbohydrates, and this therapy should be considered as an alternative to the intravenous therapy for preoperative fluid and electrolyte management in selected surgical patients in whom there is no reason to suspect delayed gastric emptying.

Randomized Controlled TrialInsertion length and resistance during advancing of epidural catheter.
The migration of an epidural catheter into the intravascular and subarachnoid spaces sometimes occurs. This study was designed to investigate where the resistance was felt during the advancing of the catheter into the epidural space and whether the length of catheter advanced in the epidural space affected the incidence of catheter migration. ⋯ At approximately 2.5 cm in the epidural space, advancing an epidural catheter causes resistance. Further advancing past this point may cause migration of the catheter into the vessels, or the coiling of the catheter.
