AIM: Peritonectomy procedures with intraperitoneal chemohyperthermia are an effective but costly treatment for peritoneal carcinomatosis (PC). Consequently a proper selection of patients is necessary. We evaluated the benefit of MRI prior to surgery, in the detection of two of the main surgery contraindications: bulky mesenteric tumors and bladder implants. METHODS: Three experts retrospectively reviewed abdominal and pelvic MRI from 19 cases of surgically proved PC (ovary: 7; colorectal: 7; gastric: 2; pseudomyxoma peritonei: 2; appendix: 1). RESULTS: Mesenteric tumors were always identified as hypersignal masses on axial and coronal fat suppression gadolinium-enhanced T1 images (n=3). Three out of five bladder implants were detected. The two cases of bladder implants that were not detected on MRI were missed because the bladder was not filled. The best sequence for the detection of bladder involvement was axial T2-weighted images with bladder filling. CONCLUSIONS: Evaluating the preoperative resectability of PC is crucial for patient management. MRI seems to reliably detect bulky mesenteric tumors and bladder implants on condition the bladder is filled and appropriate sequences are used. 相似文献

This prospective study was designed to test the hypothesis that intraoperative hypothermia occurring during abdominal aortic surgery and vasodilator therapy used to avoid severe consequences of aortic clamping could both disturb the mixed venous oxygen saturation signal (SVO2). Twenty high risk surgical patients, ASA physical status II or III, were catheterized with the standard pulmonary artery catheter; SVO2 was determined by direct spectrophotometric measurements of oxygen haemoglobin concentration of serial samples. The relationships between SVO2, haemodynamic, metabolic variables and core temperature were analyzed. Haemodynamic values and oxygen transport were stable while inadequate tissue oxygenation occurred. A significant correlation was found between SVO2 and CI (r = 0.59, p less than 0.01), SVO2 and SVRI (r = -0.4, p less than 0.01), SVO2 and CT (r = -0.46, p less than 0.01), SVO2 and VO2 (r = -0.76, p less than 0.001). SVO2 and Qs/Qt (r = 0.83, p less than 0.001), SVO2 and EO2 (r = -0.75, p less than 0.001. No correlation was observed between SVO2 and lactacidemia (r = 0.04, p less than 0.05). Satisfactory haemodynamic stability and oxygen transport steady-state were the main conditions for a significant correlation between SVO2 and haemodynamic factors. However, there was no correlation between SVO2 and inadequate tissue oxygenation. SVO2 reflected only oxygen extraction. Intraoperative hypothermia provided an increased haemoglobin affinity for oxygen. Vasodilator therapy which allowed a decrease in systemic vascular resistance produced an increase in the left-right shunt and in venous oxygen admission. Thus hypothermia and vasodilator therapy could be both responsible for the elevated SVO2 occurring during infrarenal abdominal aortic surgery. 相似文献

The cystic fibrosis transmembrane conductance regulator (CFTR) gene of 600 unrelated cystic fibrosis (CF) patients living in France (excluding Brittany) was screened for 105 different mutations. This analysis resulted in the identification of 86% of the CF alleles and complete genotyping of 76% of the patients. The most frequent mutations in this population after delta F508 (69% of the CF chromosomes) are G542X (3.3%), N1303K (1.8%), W1282X (1.5%), 1717-1G-->A (1.3%), 2184delA + 2183 A-->G (0.9%), and R553X (0.8%). 相似文献

Although the drugs known as "calcium antagonists" exert inhibitory actions on vascular smooth muscle, there are no quantitative data concerning the clinical use of these vasodilator agents in human subarachnoid haemorrhage. In the present clinical study, we have measured the effects of nifedipine (20 mg tablet) on common carotid artery diameter (D) blood flow velocity (V) common carotid blood flow (CCBF) as an index of cerebral blood flow, systolic (Qs) and diastolic (Qd) blood flow fractions using a pulsed Doppler apparatus and on carotid arterial pressure (CAP), heart rate (HR) and oxygen consumption (VO2). Eight patients with subarachnoid haemorrhage were studied during anaesthesia for cerebral angiography. Thirty minutes after sublingual nifedipine, diameter (P less than 0.05), blood flow velocity (P less than 0.001), CCBF (P less than 0.001), Qs (P less than 0.05), and Qd (P less than 0.05) increased with a decrease in Qs/Qd ratio (P less than 0.05). carotid vascular resistance (CVR) fell (P less than 0.02) and oxygen consumption of the brain increased (P less than 0.01). Systolic, diastolic, and mean carotid blood pressure, heart rate, and arteriovenous difference in oxygen were unchanged. The increase in CCBF was closely correlated with the vascular resistance in the control state (r = 0.928, P less than 0.001) and with oxygen consumption (r = 0.869, P less than 0.001). We conclude that in vivo, nifedipine exerts a preferential action on cerebral vessels, vasodilating large arteries and arterioles. This action is more powerful if the vessels are already vasoconstricted. Thus, the use of nifedipine could be fruitful in cerebral ischaemia that is secondary to subarachnoid haemorrhage. 相似文献

As hospitals move from image advertising to ads that highlight specific services, they need to consider a potential "second audience"--their employees. In an exploratory study of nurses and their opinions of hospital advertising, the potential impact of ads on nurses' role congruence and clarity and on their feelings of being valued by the hospital was examined. Specific recommendations for hospital advertising are offered. 相似文献

BACKGROUND: Adequate vocal cord paralysis and full recovery of laryngeal muscle function are important when muscle relaxants are used perioperatively. This study was designed to compare the effects of vecuronium and rocuronium at the vocal cord abductor and adductor muscles and the anterior tibial muscle in cats. METHODS: Twelve adult cats were studied under pentobarbitone-N2O/O2-anesthesia. After supramaximal electrical stimulation of the peroneal nerve and the recurrent laryngeal nerve (0.1 Hz and intermittent train-of-four) evoked electromyographic responses were obtained from the anterior tibial muscle, the posterior cricoarytenoid muscle (vocal cord abductor) and two vocal cord adductor muscles, the lateral cricoarytenoid and the vocal muscle. Six cats received bolus doses of increasing size of vecuronium (ED90 22.5 microg x kg(-1)) and six cats rocuronium (ED90 90 microg x kg(-1)). RESULTS: Equipotent doses of vecuronium and rocuronium caused a similar degree of paralysis in all muscles (vecuronium ED90: 70% blockade at the posterior cricoarytenoid, 83% at the lateral cricoarytenoid, 84% at the vocal muscle and 90% at the anterior tibial muscle; rocuronium ED90: 71% at the posterior cricoarytenoid, 67% at the lateral cricoarytenoid, 78% at the vocal muscle and 90% at the anterior tibial muscle; vecuronium 2 x ED90: 93% blockade at the posterior cricoarytenoid, 95% at the lateral cricoarytenoid, 97% at the vocal muscle and 99% at the anterior tibial muscle; rocuronium 2 x ED90: 89% blockade at the posterior and lateral cricoarytenoid, 93% at the vocal muscle and 100% at the anterior tibial muscle). Onset time was significantly shorter at the posterior cricoarytenoid muscle (290 s) compared to the lateral cricoarytenoid muscle (400 s) after vecuronium ED90 and to the vocal muscle (150 s versus 210 s) after rocuronium ED90. Compared to the anterior tibial muscle (interval 25-75%: 6.5 min after vecuronium 2 x ED90 and 3.3 min after rocuronium 2 x ED90 and to the posterior cricoarytenoid muscle (interval 25-75%: 7 min after vecuronium 2 x ED90 and 4.3 min after rocuronium 2 x ED90), recovery of laryngeal adductor muscle function was markedly delayed with both neuromuscular blocking drugs (interval 25-75% at the lateral cricoarytenoid and vocal muscle: 14 min and 15.8 min after vecuronium 2 x ED90 and 10.3 min and 11.6 min after rocuronium 2 x ED90 respectively). CONCLUSION: In cats, the time course of neuromuscular blockade after vecuronium and rocuronium differs in antagonistic laryngeal muscles. The protective laryngeal function of glottis closure recovers later than vocal cord abduction after both vecuronium and rocuronium. 相似文献

Treatment of peritoneal carcinomatosis in gastric cancers 总被引:7,自引:0,他引:7
Peritoneal carcinomatosis may occur after curative surgery of any gastrointestinal carcinoma, but it is however the most frequent form of evolution after curative resection of gastric carcinoma and is present at the time of surgery in many cases. This locoregional extension of cancer has a poor prognosis, with a great mortality and a poor quality of life. It is sometimes considered of such a poor prognosis that patients do not go through any resection or palliative procedure. Techniques of radiotherapy, chemotherapy and intraperitoneal chemotherapy have been used with moderate clinical efficacy. Since the 1990s, intraoperative hyperthermic peritoneal chemotherapy combined with comprehensive cytoreductive surgery has been proposed to improve prognosis of patients with peritoneal carcinomatosis from gastric origin as well as carcinomatosis from colorectal origin or pseudomyxoma peritonei. 相似文献
