Statistically significant increases of QTd and QTcd, which are associated with an increased risk of arrhythmias and cardiac events, occur during CO(2) insufflation in both high-pressure and low-pressure pneumoperitoneums. QTd and QTcd were significantly higher in the high-pressure pneumoperitoneum group than they were in the low-pressure pneumoperitoneum group. QT interval changes were not related to anesthetic agents, surgical stress, hypercapnia, or duration of CO(2) insufflation. Increased intra-abdominal pressure may have caused these changes.

BackgroundThe aim of this study was to investigate the protective effects of methylprednisolone (Pn), which is a potent anti-inflammatory agent, and pheniramine maleate (Ph), which is an antihistaminic with some anti-inflammatory effects, on reperfusion injury in brain developing after ischemia of the left lower extremity of rats.Material/MethodsTwenty-eight randomly selected male Sprague-Dawley rats were divided into 4 groups: Group 1 was the control group, Group 2 was the sham group (I/R), Rats in Group 3 were subjected to I/R and given Ph, and rats in Group 4 were subjected to I/R and given Pn. A tourniquet was applied at the level of left groin region of subjects in the I/R group after induction of anesthesia. One h of ischemia was performed with no drug administration. In the Ph group, half of a total dose of 10 mg/kg Ph was administered intraperitoneally before ischemia and the remaining half before reperfusion. In the Pn group, subjects received a single dose of 50 mg/kg Pn intraperitoneally at the 30th min of ischemia. Brains of all subjects were removed after 24 h for examination.ResultsMalondialdehyde (MDA) levels of the prefrontal cortex were significantly lower in the Ph group than in the I/R group (p<0.05). Superoxide dismutase (SOD) and glutathione peroxidase (GPx) enzyme activities were found to be significantly higher in the Ph group than in the I/R group (p<0.05). Histological examination demonstrated that Ph had protective effects against I/R injury developing in the brain tissue.ConclusionsPh has a protective effect against ischemia/reperfusion injury created experimentally in rat brains.

Arterial cannulation for haemodynamic monitoring has become a routine procedure in the clinical management of critically ill adults. Thrombosis is the most common complication of this procedure. We report the case of a patient with multiple traumatic injuries in which radial artery cannulation was associated with compartment syndrome of the forearm and hand.

INTRODUCTIONSurgery is the only treatment option for familial adenomatous polyposis (FAP). Aim of surgery in FAP is to minimize colorectal cancer risk without need for permanent stoma. There are especially two operation options; Total colectomy with ileorectal anastomosis (IRA) and total proctocolectomy with ileo-pouch anal anastomosis (IPAA). We report here a patient with FAP who had resection via rectal eversion just over the dentate line under direct visualization and ileoanal-J pouch anastomosis by double-stapler technique.PRESENTATION OF CASEA 40 yr. old female patient with FAP underwent surgery. Firstly, colon and the rectum mobilized completely, and then from the 10 cm. proximal to the ileo-caecal valve to the recto-sigmoid junction total colectomy was performed. Rectum was everted by a grasping forceps which was introduced through the anus and then resection was performed by a linear stapler just over the dentate line. A stapled J-shaped ileal reservoir construction followed by intraluminal stapler-facilitated ileoanal anastomosis. Follow up at six months anal sphincter function was found normal.DISCUSSIONThere is only surgical management option for FAP patients up to now. Total colectomy with IRA and restorative proctocolectomy with IPAA is surgical options for FAP patients that avoid the need for a permanent stoma. Anorectal eversion may be used in the surgical treatment of FAP, chronic ulcerative colitis and early stage distal rectal cancer patients.CONCLUSIONJ-pouch ileoanal anastomosis can safely be performed by rectal eversion and double stapler technique in FAP patients.
