Review Meta Analysis
Ropivacaine for continuous wound infusion for postoperative pain management: a systematic review and meta-analysis of randomized controlled trials.
The use of continuous wound infusion (CWI) of local anaesthetics has been suggested as a safe and effective alternative technique to epidural anaesthesia/analgesia that allows surgeons to provide postoperative pain relief while reducing opioid consumption and associated adverse events. A previous meta-analysis by Liu et al. [Am Coll Surg 2006;203:914-932] reported results mainly from studies of bupivacaine. Subsequently, several new randomized controlled trials (RCTs) of ropivacaine have been published. This systematic review and quantitative meta-analysis evaluates the efficacy of ropivacaine for CWI. ⋯ This systematic review and meta-analysis presents substantial evidence that ropivacaine provides clinically meaningful reductions in opioid use and pain outcomes. Ropivacaine CWI is effective for postoperative pain management in a wide range of surgical procedures.

Protective loop ileostomies in colorectal surgery are constructed to reduce morbidity and reinterventions related to the primary operation. However, ileostomies are associated with stoma-related morbidity and postoperative complications following reversal surgery. Dutch national data show increased use of loop ileostomies in colorectal surgery for cancer justifying an adequate assessment of its morbidity. This study was undertaken to investigate morbidity associated with protective loop ileostomies in colorectal surgery. ⋯ Construction of loop ileostomies in left-sided colonic or rectal resection is associated with a low risk for anastomotic leakage at the expense of substantial stoma-related morbidity and morbidity related to reversal surgery. More accurate identification of colorectal cancer patients benefitting from protective loop ileostomy seems to be warranted.

Regardless of whether alone or in combination, cecal ligation and puncture (CLP) is the most commonly used model to emulate human polymicrobial sepsis. Numerous CLP studies have shown that female mice survive better than males. In adult mice, this effect may be partly due to the unequal cecum mass (larger in males), as cecum ligation is frequently not size standardized. Comparing two ligation approaches, we investigated whether cecum size influences gender-specific outcome differences. ⋯ Standardization by AP-L did not eliminate the gender-specific difference in mortality due to posttraumatic sepsis. The greater cecum length/filling in middle-aged male mice was not responsible for their inferior survival compared to females.

To identify the risk factors for clinically relevant pancreatic fistula after distal pancreatectomy with a flexible cartridge stapler, TL60. ⋯ Distal pancreatectomy with the use of the TL60 stapler eliminated the risk of pancreas-related factors for the occurrence of clinically relevant pancreatic fistula.

During acellular replacement of an acute blood loss, hyperoxic ventilation (HV) increases the amount of O2 physically dissolved in the plasma and thereby improves O2 supply to the tissues. While this effect could be demonstrated for HV with inspiratory O2 fraction (FiO2) 0.6, it was unclear whether HV with pure oxygen (FiO2 1.0) would have an additional effect on the physiological limit of acute normovolemic anemia. ⋯ HV with FiO2 1.0 maintains O2 supply to tissues during extensive blood-for-HES exchange. In acute situations, where profound anemia must be tolerated (e.g. bridging an acute blood loss until red blood cells become available for transfusion), O2 physically dissolved in the plasma becomes an essential source of oxygen. However, compromised cardiovascular performance might require additional treatment.
