Low Systemic Vascular Resistance After Cardiopulmonary Bypass: Incidence, Etiology, and Clinical Importance

JOURNAL OF CARDIAC SURGERY, Issue 5 2000
T. Carrel M.D.
The etiology is not completely elucidated and the clinical importance remains speculative. Methods: In this prospective clinical trial, we assessed the incidence of postoperative low systemic vascular resistance in 800 consecutive patients undergoing elective coronary artery bypass grafting and/or valve replacement. We have attempted to identify the predictive factors responsible for the presence of low systemic vascular resistance and we have examined the subsequent postoperative outcome of those patients who developed early postoperative vasoplegia. The severity of vasoplegia was divided into three groups according either to the value of systemic resistance and/or the dose of vasoconstrictive agents necessary to correct the hemodynamic. Results: Six hundred twenty-five patients (78.1%) did not develop vasoplegia, 115 patients (14.4%) developed a mild vasoplegia, and 60 patients (7.5%) suffered from severe vasoplegia. Low systemic vascular resistance did not affect hospital mortality but was the cause for delayed extubation and prolonged stay on the intensive care unit IICU). Logistic regression analysis identified temperature and duration of cardiopulmonary bypass, total cardioplegic volume infused, reduced left ventricular function, and preoperative treatment with angiotensin-converting enzyme (ACE)-inhibitors, out of 25 parameters, as predictive factors for early postoperative vasoplegia. Conclusion. The occurrence of low systemic vascular resistance following cardiopulmonary bypass is as high as 21.8%. The etiology of this clinical condition is most probably multifactorial. Mortality is not affected by vasoplegia, but there is a trend to higher morbidity and prolonged stay in the ICU. [source]


Complete pathologic response after preoperative rectal cancer chemoradiotherapy

ANZ JOURNAL OF SURGERY, Issue 6 2009

Abstract Background:, Following preoperative treatment of rectal cancer with chemoradiotherapy (CRT), a complete pathological response (CPR) can be seen in the surgical specimen. The aim of this study was to assess the outcome of these patients as compared with those who did not have a complete response. Methods:, A retrospective study of the outcome of patients managed with preoperative CRT for their rectal cancer was conducted. Results:, Between November 1998 and July 2004, there were 530 new presentations of rectal cancer at The Queen Elizabeth and Royal Adelaide hospitals. Forty of these patients (7.5%) were treated with long-course preoperative CRT. After resection, a CPR was seen in seven patients (17.5%). These patients were all disease free at January 2006 after a median follow-up of 6.0 years (range 1.42,7.02 years). One patient had died from non-tumour-/surgery-related causes. Tumour recurrence, but not mortality, in this group was superior to the comparison group of patients without a CPR. Conclusions:, None of our patients who had a CPR after preoperative CRT have recurred or died from their disease. [source]


Health-related quality of life during neoadjuvant treatment and surgery for localized esophageal carcinoma

CANCER, Issue 9 2005
Jane M. Blazeby B.Sc., M.D.
Abstract BACKGROUND Esophagectomy has a negative influence on health-related quality of life (HRQL) during the first postoperative year, but it is not known how chemotherapy or chemoradiotherapy treatment before surgery affects HRQL. The current study examined HRQL during preoperative chemotherapy/chemoradiotherapy treatment and compared postoperative recovery of HRQL in patients undergoing combined treatment with patients undergoing surgery alone. METHODS One hundred three patients completed standardized HRQL measures before and during neoadjuvant treatment and before and after surgery. Mean HRQL scores were calculated and preoperative scores were used to model postoperative ratings using linear regression. RESULTS Deterioration in most aspects of HRQL occurred during preoperative chemotherapy. Patients proceeding to concomitant radiotherapy further deteriorated with specific problems with reflux symptoms and role function (difference between means >15, P < 0.01). After neoadjuvant treatment, but before surgery, HRQL returned to baseline levels. Six weeks after surgery, patients reported marked reductions in physical, role, and social function (difference between means > 30, P < 0.01) and increase in fatigue, nausea and emesis, pain, dyspnea, appetite loss, and coughing (difference between means > 15, P < 0.01). Recovery of HRQL was not hampered by preoperative treatment, and fewer problems with postoperative nausea, emesis, and dysphagia were reported by patients who had undergone neoadjuvant treatment compared with patients who had undergone surgery alone. CONCLUSIONS Preoperative chemotherapy or chemoradiotherapy had a negative impact on HRQL that was restored in patients proceeding to surgery. Recovery of HRQL after esophagectomy was not impaired by neoadjuvant treatment. These results supported the use of neoadjuvant treatment before surgery. Cancer 2005. © 2005 American Cancer Society.

Patient preparation before surgery for cholangiocarcinoma

HPB, Issue 3 2008
E. Oussoultzoglou
Abstract Aim. Multiorgan dysfunction is often encountered in jaundiced patients and may compromise the postoperative outcome after liver resection for cholangiocarcinoma (CCA). The aim of the present study was to elucidate evidence-based medicine regarding the benefit of the available preoperative treatments currently used for the preparation of patients before surgery for hilar CCA. Material and methods. An electronic search using the Medline database was performed to identify relevant articles relating to renal dysfunction, bacterial translocation, hemostasis impairment, malnutrition, liver failure, and postoperative outcome in jaundiced patients undergoing liver resection for CCA. Results. There is grade B evidence to expand the extracellular water volume and to administer oral synbiotic supplements. Intravenous vitamin K administration is an effective treatment. Perioperative nutritional support should be administered preferably by the enteral route in severely malnourished patients with compromised liver function undergoing extended liver resection (grade A evidence). There is only grade C evidence to recommend a portal vein embolization in patients with CCA when the future remnant liver volume is <40%. Conclusions. A simplified scheme that might be useful in the management of patients presenting with obstructive jaundice was presented. Despite surgical technique improvements, preparation of patients for surgery will continue to be one of the major determinants for the postoperative prognosis of jaundiced patients. [source]
