Diagnostic evaluation and management of patients with rectus sheath hematoma. A retrospective study.
Rectus sheath hematoma (RSH) is an uncommon cause of acute abdominal pain. It may mimic a wide variety of intraabdominal disorders thus frequently leading to delay in treatment, increased morbidity or even in an unnecessary surgery. ⋯ RSH should be considered in the differential diagnosis of the elderly patients under anticoagulation therapy presenting with acute abdominal pain and a palpable mass. CT is the diagnostic modality of choice. Conservative treatment is feasible in most cases. Early diagnosis is mandatory in order to avoid morbidity or unnecessary surgery. In order to prevent a traumatic RSH, trocar insertion under direct vision during laparoscopic surgery and careful attention in the abdominal administration of LMWH are essential.

Comparative Study
Peri-operative antibiotic prophylaxis: adherence to guidelines and effects of educational intervention.
This study was aimed to determine the propriety of perioperative antimicrobial prophylaxis, to evaluate the effects of a training intervention on correction. ⋯ Although this educational intervention study achieved improvements in indications, choice, and dosing of surgical antimicrobial prophylaxis, it failed to improve prolonged use and total compliance rate, and to lower the costs sufficiently. It will probably provide better results by means of compulsory measures for surgeons to comply with available protocols and guidelines, as well as education programs, in order to change the antibiotic utility habits on surgical prophylaxis and to achieve accurate prophylactic administrations.

The effect of vasopressors on the healing of gastrointestinal anastomoses is still controversial. The purpose of our study was to research the relationship between dose of dopamine, which is used generally as a vasopressor in shock status, and anastomotic leak in colonic surgery. ⋯ Although vasopressors appeared to increase the risk of anastomotic leakage as a result of splanchnic vasoconstriction, deterioration of microcirculation, and local hypoxia, we found that BPA were increased with high doses of vasopressor. We speculated that the use of vasopressors without shock might increase blood supply to the anastomotic line by increasing cardiac output.

Randomized Controlled Trial Comparative Study
Prophylactic antibiotics in open mesh repair of inguinal hernia - a randomized controlled trial.
The role of prophylactic antibiotics in mesh repair of inguinal hernia is unclear. A Cochrane meta-analysis in 2005 concluded that "antibiotic prophylaxis for elective inguinal hernia repair cannot be firmly recommended or discarded" and "further studies are needed, particularly on the use for mesh repair." So, we designed a study to define the role of prophylactic antibiotics in mesh repair of inguinal hernia. We conducted a prospective, randomized, double-blind, trial comparing wound infection rates in 450 patients (225 received intravenous Cefazolin, 225 received a placebo) undergoing primary inguinal hernia repair electively using polypropylene mesh. 334 patients who completed a followup period of one month were analyzed. ⋯ Most of the infections occurred between the 7th and 12th post-operative day after discharge from the hospital. Antibiotic prophylaxis was associated with decreased incidence of wound infection when compared to control group, but the difference was not statistically significant. Based on our results we do not recommend the routine use of antibiotic prophylaxis in elective mesh repair of inguinal hernias.

Peri-operative monitoring technology has made great strides in the last 20 years with the introduction of minimally invasive devices to measure inter alia stroke volume, cardiac output, depth of anaesthesia and cerebral and tissue oxygen monitoring. Despite these technological advances, peri-operative management of the high risk major surgery patient has remained virtually unchanged. The vast majority of patients undergo a pre-operative assessment which is neither designed to quantify functional capacity nor predict outcome. ⋯ It is perhaps not surprising that outcome still remains poor in high-risk patients.(1) In this review, we will briefly describe the role of peri-operative optimization, some of the available monitors and indicate how their combined use might be beneficial in managing the high-risk surgical patient. We believe that although there is now evidence to suggest that the use of individual new monitors (such as assessment of fluid status, depth of anaesthesia, tissue oxygenation and blood flow) can influence outcome, it will only be their combination that will radically improve the peri-operative management and outcome of high-risk surgical patients. It is a matter of some urgency that large scale, prospective and collaborative studies be designed, funded and executed to prove or disprove this hypothesis.
