Review Meta Analysis
Review article: the role of anticonvulsant drugs in postoperative pain management: a bench-to-bedside perspective.
Anticonvulsant drugs are effective in the treatment of chronic neuropathic pain but were not, until recently, thought to be useful in more acute conditions such as postoperative pain. However, similar to nerve injury, surgical tissue injury is known to produce neuroplastic changes leading to spinal sensitization and the expression of stimulus-evoked hyperalgesia and allodynia. Pharmacological effects of anticonvulsant drugs which may be important in the modulation of these postoperative neural changes include suppression of sodium channel, calcium channel and glutamate receptor activity at peripheral, spinal and supraspinal sites. The purpose of this article is to review preclinical evidence and clinical trial data describing the efficacy and safety of anticonvulsant drugs in the setting of postoperative pain management. ⋯ Given the incomplete efficacy of currently available non-opioid analgesics, and the identified benefits of opioid sparing, anticonvulsant medications may be useful adjuncts for postoperative analgesia. Further research in this field is warranted.

Randomized Controlled Trial Comparative Study
Lower flange modification improves performance of the Macintosh, but not the Miller laryngoscope blade.
In order to minimize the potential for dental damage and to improve laryngeal visualization during tracheal intubation, two commonly used laryngoscope blades were modified and compared in a clinical setting: the Miller laryngoscope blade and the Macintosh laryngoscope blade. Modified versions of both laryngoscope blades with a lowered heel (Callander modification) at the proximal end of the blade were compared to standard blades. ⋯ A reduction of the proximal flange of a Miller blade decreases the blade's effectiveness for laryngeal visualization, whereas a similar modification of a Macintosh blade increases blade-tooth distance, decreases the number of blade-tooth contacts and provides a better laryngeal view.

To review laboratory investigations required for the diagnosis of a constitutional or acquired defect of hemostasis before surgery, or during the perioperative period in context of rapid evolution and possible therapeutic adjustment. ⋯ The investigation of hemostasis at the central laboratory and POC testing have distinct objectives. The utility of the former for the diagnosis and the adjustment of therapeutics have been well demonstrated. In contrast, the experience with POC testing is relatively recent, and its utility for patient management remains to be demonstrated in proper clinical trials.

Randomized Controlled Trial Comparative Study
Laparoscopy for colectomy accelerates restoration of bowel function when using patient controlled analgesia.
A standardized care plan incorporating patient-controlled analgesia with iv morphine and a non-accelerated feeding schedule following colectomy was used to compare return of bowel function and hospital discharge times following surgery done by laparoscopy or laparotomy ⋯ When patient-controlled analgesia with morphine and a traditional perioperative program are used, a laparoscopic approach to colon surgery promotes earlier restoration of bowel function and more rapid hospital discharge in comparison to resection by laparotomy.

To review the pathophysiology of coagulopathy in massively transfused, adult and previously hemostatically competent patients in both elective surgical and trauma settings, and to recommend the most appropriate treatment strategies. ⋯ Coagulopathy associated with massive transfusion remains an important clinical problem. It is an intricate, multifactorial and multicellular event. Treatment strategies include the maintenance of adequate tissue perfusion, the correction of hypothermia and anemia, and the use of hemostatic blood products to correct microvascular bleeding.
