Background: Pediatric craniofacial reconstruction (CFR) procedures involve wide scalp dissections with multiple osteotomies and have been associated with significant morbidity. The aim of this study was to document the incidence of clinically important problems, particularly related to blood loss, and perform a risk factor analysis. Methods: Records of all patients who underwent craniofacial surgery at the Children’s Hospital of Philadelphia between December 1, 2001 and January 1, 2006 were reviewed. Data were collected from the electronic anesthesia record, intensive care unit (ICU) progress notes, and discharge summary. All intraoperative laboratory values and all laboratory values obtained upon arrival in the ICU were recorded. A multivariable analysis was performed to evaluate associations between elements of intraoperative management and the following clinical outcomes: intraoperative hypotension, intraoperative metabolic acidosis, presence of a postoperative coagulation test abnormality, and postoperative administration of hemostatic blood products. Results: Data for 159 patients were reviewed. The mean volume of packed red blood cells transfused intraoperatively was 51 ml·kg?1. Multivariable analysis revealed that intraoperative administration of albumin was strongly correlated with both an increased incidence of postoperative coagulation derangements and postoperative administration of hemostatic blood products (Odds Ratio 5.9, 2.8, respectively), while intraoperative fresh frozen plasma (FFP) administration was associated with an opposite effect (Odds Ratio 0.94, 0.97, respectively). Conclusions: In pediatric CFR procedures where the volume of blood loss routinely exceeds one blood volume, intraoperative administration of FFP favorably impacted postoperative laboratory coagulation parameters. 相似文献

A series of 14 patients with intracerebral hemorrhage after carotid endarterectomy is reviewed. This complication occurred in 0.6% of 2362 consecutive carotid endarterectomies performed at the Mayo Clinic from 1972 through 1986. All hemorrhages occurred within the first 2 weeks after operation and were ipsilateral to the side of the operation. Eight patients died, and only two made a good recovery. Significant risk factors are hypertension and chronic hemispheric hypoperfusion with impaired autoregulation. The "normal pressure-hyperperfusion breakthrough" syndrome was considered to be operative in 12 of the 14 patients. Nine patients had documented hyperperfusion (at least 100% increase of baseline cerebral blood flow) at the time of surgery. In an additional three patients, normal perfusion-pressure breakthrough was inferred by the clinical course and radiological findings, as well as by the absence of alternative explanations. Patients at risk for postendarterectomy intracerebral hemorrhage include those who have a clinical history suggestive of hemodynamic cerebral ischemia, severe carotid stenosis with limited hemispheric collateral flow, and postendarterectomy hyperperfusion, as measured by intraoperative cerebral blood flow. To minimize the risk of hemorrhage in these patients, strict maintenance of blood pressure at normotensive or even relatively hypotensive levels during the intraoperative and early postoperative periods is advised. 相似文献

Laparoscopic partial nephrectomy (LPN) is increasingly becoming a definitive therapeutic option for the treatment of small (less than 4 cm) and select moderate-sized (less than 7 cm) renal tumors. Postoperative hemorrhage and urine leak are the most pertinent complications after nephron-sparing surgery, open or laparoscopic. To our knowledge, the risk factors of urine leaks after retroperitoneal LPN have not been studied. We retrospectively analyzed our experience with retroperitoneal LPN to determine risk factors for postoperative urine leak complications. The records of 236 patients who underwent retroperitoneal LPN for renal tumor from March 2003 to October 2010 were reviewed retrospectively. Urine leak was strictly defined as continued urine output from the drain after postoperative day 2. In our series, 39 patients (16.5%) had urine leak complications. On multivariate analysis, mean estimated blood loss (p = 0.0120) and computed tomography angiogram (CTA) examination (p = 0.0286) were independent predictive factors of urine leaks. Moreover, the intraoperative blood loss was significantly reduced in patients undergoing CTA examination (p = 0.0375). Our investigation showed that factors such as intraoperative blood loss and CTA examination are predictors of urine leaks after retroperitoneal LPN. Less intraoperative blood loss to obtain a clear operative field and meticulous suturing technique are necessary to reduce urine leak probability. 相似文献

Early postoperative hemorrhage requiring urgent surgical reintervention after orthotopic liver transplantation 总被引:1,自引:0,他引:1
Hemorrhage is a common complication in the early postoperative period after orthotopic liver transplantation (OLT) and surgical reintervention may be necessary. We sought to assess the incidence as well as to identify potential risk factors for bleeding requiring surgical reintervention in the early postoperative period. From January 2003 to December 2005, we retrospectively reviewed the courses of 261 patients who underwent OLT. We analyzed the pretransplantation parameters, transplantation features, and clinical data for surgical reintervention due to early postoperative hemorrhage. Twenty-two of 261 patients (8.4%) had early postoperative hemorrhage requiring urgent surgical reintervention during the initial hospital stay. In-hospital mortality of the patients with hemorrhage (9/22; 41%) was significantly higher than that of other patients (29/239; 12.1%; P < .001). The surgical problem was the main cause of hemorrhage (18/22; 81.8%). More intraoperative blood transfusions were necessary for patients with hemorrhage than for other patients. Furthermore, a greater number of blood transfusions, including red blood cells, plasma, and platelet concentrates, during the transplantation procedure correlated with a greater mortality. In conclusion, early postoperative hemorrhage requiring urgent surgical reintervention is a severe complication with a high mortality. It is mainly caused by errors in surgical technique. Blood transfusion during transplantation was correlated with a higher mortality. 相似文献

Transcranial Doppler techniques were used to monitor blood velocity in cerebral arteries continuously during 14 neurosurgical operations performed on 13 patients, including 12 craniotomies. Stable Doppler signals were obtained for prolonged periods of time, and they correlated with intraoperative events. Monitoring during spontaneous blood pressure and CO2 variations allowed assessment of autoregulatory capacity. In particular, 5 of the 7 patients receiving craniotomy for aneurysmal subarachnoid hemorrhage had impaired autoregulation. A 30 to 50% decrease in Doppler velocities was seen in 7 patients after etomidate administration. Early experience suggests that transcranial Doppler monitoring during craniotomy is feasible and can indicate the effects of operative events on blood flow as well as provide an assessment of cerebral autoregulation. 相似文献

We report a case of moyamoya disease manifesting as asymptomatic intracerebral hemorrhage due to postoperative cerebral hyperperfusion, despite the prophylactic intensive blood pressure control. This 35-year-old man initially suffered from right upper quadrantanopsia and was found to have cerebral infarction in the left occipital lobe due to moyamoya disease. He also manifested preoperatively a small intracerebral hemorrhage at the left caudate nucleus. The left cerebral hemisphere showed apparent hemodynamic compromise, thus he underwent left superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis with indirect pial synangiosis. He was subjected to prophylactic strict blood pressure control postoperatively to avoid hyperperfusion syndrome. The N-isopropyl-p-123I-Iodoamphetamine SPECT (123I-IMP-SPECT) 1 day after surgery showed intense increase in cerebral blood flow (CBF) at the site of the anastomosis, and further blood pressure lowering was attempted. He did not suffer from neurologic deterioration during the postoperative period, while computed tomography (CT) 7 days after surgery revealed asymptomatic intracerebral hematoma (ICH) at the subcortex under the site of the anastomosis. Cerebral hyperperfusion is a potential complication of revascularization surgery for moyamoya disease. Accurate diagnosis and proper management of hyperperfusion are essential to avoid deleterious neurologic event due to hyperperfusion. 相似文献

In order to apply adequate postoperative management of patients in the orthopedic surgery, the in vivo effects of the operations were investigated in the present study, from various viewpoints such as circulatory functions, metabolism of proteins, and hepatic and renal functions. In addition, the circulating blood volumes were determined in order to know the variations in the amount of blood loss from the operated regions during and after operations so as to improve the operative and postoperative management. On the basis of the results, the countermeasures against the adverse variations in blood volume were also investigated. Pediatric patients were found to be prone to develop more appreciable systemic postoperative reactions than those in adult ages, especially so in those of circulatory system, peripheral blood, hepatic functions, and protein metabolism, and also prone to be more affected by operative procedures. Senile patients were found to be prone to have less reserve capacity in circulation, peripheral blood, renal functions, and protein metabolism, and also prone to show delayed postoperative reactions and slower recoveries. The results of measurement of circulating blood volume in pre- and postoperations revealed that the loss of circulating blood in most patients was greater than the bleeding weight during the operation measured by gause count, and that, on the day following the operation, the blood volume was reduced by about 10-15% than those immediately after the operation. It was concluded that, as a whole, no changes causing serious deviation from the normal physiological ranges occur except in pediatric and senile patients. On the basis of the above findings, most appreciable systemic postoperative reactions of the operative procedures in orthopedic surgery would be attributed to by loss of blood volume during operations and that the postoperative hemorrhage from bone structure (which is usually difficult to control) or the postoperative hemorrhage after removal of air tourniquet would be almost negligible. 相似文献

The newest therapy for cerebral aneurysm is the Guglielmi detachable coil (GDC). The authors describe the anesthetic management of two patients with intraoperative subarachnoid hemorrhage during Guglielmi coil placement. Various treatments for intraoperative hemorrhage are discussed, as are other common complications that can occur during placement of intravascular, intracranial coils. The placement of a ventriculostomy was a major contributing factor in the good outcome of both patients. Consideration should be given to placement of a ventriculostomy before the GDC procedure. Although the GDC procedure offers much promise, it is not a benign procedure and has its own set of complications that will no doubt challenge the neuroanesthesiologist. 相似文献

Preoperative preparation in pheochromocytoma is usually performed by alpha-adrenergic blockers. We retrospectively reviewed the efficiency of phenoxybenzamine, prazosin, and doxazosin in preoperative preparation. Phenoxybenzamine was used for preoperative preparation of 21 pheochromocytoma patients, prazosin was used in 11 patients, and doxazosin was used in 17 patients. Intraoperative and early postoperative blood pressure records and postoperative volume replacement records were reviewed. Intraoperative hypertension occurred in 17 patients in the phenoxybenzamine group (81%), eight patients in the prazosin group (73%), and 14 patients in the doxazosin group (82%). There was no statistical difference among the groups (P > 0.05). There was also no significant difference between postoperative blood pressure measurements and the operative and postoperative volume replacements. We have found that there were no significant difference in the operative and postoperative blood pressure and plasma volume control among the three groups. We conclude that pheochromocytoma surgery is safe with any of these preoperative medications. 相似文献

An elderly patient without evidence of major organ damage following severe hemodilution caused by massive intraoperative hemorrhage 总被引:1,自引:0,他引:1
An 82-year-old woman with hematemesis was admitted to our hospital. Diagnosis of bleeding from gastric ulcer was made and an emergency operation was performed. Although she fell into sudden hypotension, ventricular tachycardia and severe hemodilution lasting for 45 minutes (minimum hemoglobin concentration of 1.8 g x dl(-1)) caused by intraoperative massive hemorrhage, she recovered without any apparent postoperative damage in major organs. The major reasons for evading organ damage may be attributable to maintenance of blood pressure and circulatory volume, and to early medication for prevention of systemic inflammatory response syndrome or disseminated intravascular coagulation. 相似文献

The aim of the study is to investigate the risk factors identified in literature that have been associated with prolonged Negative Pressure Wound Therapy (NPWT). Our study included patients who developed local wound problems after bone or soft tissue sarcoma surgery with negative margin at our clinic between 2012 and 2018 and treated with NPWT. All patients were followed up of at least 6 months. Sex, albumin level, skin infiltration, type of wound problem, postoperative intensive care unit (ICU) requirement, and intraoperative blood loss were found to be influential factors on NPWT > 10 sessions. We conclude that treatment may be prolonged and the necessary precautions need to be taken in patients with an impaired preoperative nutritional condition, with intraoperative high amount of blood loss, and with long postoperative stays in the ICU as well as if the underlying cause for wound problem is an infection. 相似文献

OBJECT: Nitric oxide (NO) metabolism may influence vasospasm after subarachnoid hemorrhage (SAH). It has been demonstrated in recent studies that erythrocytes carry NO for release in vessels, whereas transfused erythrocytes may lack stored NO. Several converging lines of evidence also indicate that blood transfusion may exacerbate poor outcomes in some critically ill patients. In this study the authors hypothesized that patients with SAH who received red blood cell (RBC) transfusions were at greater risk for vasospasm and poor outcome. METHODS: The authors retrospectively reviewed a prospective observational database, including hospital records, computerized tomography (CT) scans, and pre- and postoperative four-vessel angiograms, in which the management methods used in 441 patients undergoing surgery for ruptured cerebral aneurysms were described. Two hundred seventy patients (61.2%) received an RBC transfusion during their hospital stay. After adjustment for Hunt and Hess grade, SAH grade on CT scans, delay between rupture and surgery, smoking status, and intraoperative aneurysm rupture, a worse outcome was more likely in patients who received intraoperative blood (odds ratio [OR] 2.44, confidence interval [CI] 1.32-4.52; 120 patients). Intraoperative RBC transfusion did not influence subsequent angiographically confirmed vasospasm (OR 0.92, CI 0.6-1.4). Worse outcome was observed in patients who received blood postoperatively (OR 1.81, CI 1.21-2.7), but not after adjustments were made for confounding variables (OR 1.48, CI 0.83-2.63). Angiographic vasospasm was observed in 217 patients and, after adjusting for confounding variables, was more frequent among patients who received postoperative RBC transfusion (OR 1.68, CI 1.02-2.75). Among patients in whom angiographically confirmed vasospasm developed there was a tendency to have received more blood than in those with no vasospasm; however, a clear dose-dependent response was not observed. CONCLUSIONS: Development of angiographically confirmed vasospasm after SAH is associated with postoperative RBC transfusion and worse outcome is associated with intraoperative RBC transfusion. Before blood is transfused, patients with SAH should be carefully assessed to determine if they are symptomatic because of anemia. 相似文献
