The development of avascular necrosis of the femoral heads following surgery for spinal stenosis may be due to hypotensive anesthesia, prone positioning on a Montreal mattress, or a combination of the two. Careful intraoperative positioning may reduce the risk of this occurring after spinal surgery.... | PMID: 14501937

IMPLICATIONS: Cardiocirculatory arrest can be induced by adenosine and maintained over several minutes by application of high positive end-expiratory pressure to allow surgical control of a near hemorrhage from a large ruptured artery. | PMID: 12873914

Vigorous intravenous fluid resuscitation has become widely accepted as the optimum management of hemorrhagic shock in trauma. There is now, however, sufficient evidence for this position to be reviewed. Hypotensive or delayed resuscitation has been postulated as a means by which the mortality associ... | PMID: 12768105

We investigated whether clonidine lessened the requirements for isoflurane, fentanyl, and labetalol to provide controlled hypotension in children who underwent oromaxillofacial surgery. We also studied preoperative sedative effects, the hemodynamic response to nasotracheal intubation, and recovery c... | PMID: 12651645

Controlled hypotension was achieved at the target mean arterial pressure (MAP) of 50 mmHg (P < 0.01) within 121 +/- 21 and 62 +/- 9 sec for remifentanil and nitroprusside respectively. MEBF decreased by 22 +/- 4 and 20 +/- 6% and preceded the decrease in MAP within 20 +/- 7 and 10 +/- 3 sec for remi... | PMID: 12620951

The time needed to reach controlled hypotension was 6 - 35 minutes and that needed to reach the normal blood pressure was 12 - 41 minutes. The propofol infusion rate and inhalation concentration of desflurane needed to maintain controlled hypotension were 51 micro g x kg(-1) x min(-1) +/- 27 micro g... | PMID: 12812664

Intraoperative bleeding is one of the major problems in endoscopic surgery of sinuses. In the case of the expanded process, still more numerous interventions are performed with general anesthesia. The objective of research is to compare intraoperative hemorrhage and the visibility of the operative f... | PMID: 14515047

The mean infusion rate of esmolol in the esmolol-ANH group was 46+/-6 micro g/kg/min (mean+/-SD), which was significantly lower than the 77+/-9 micro g/kg/min used in the esmolol group (P<0.05). The number of units of homologous blood (packed RBC) transfused perioperatively was 2.2+/-0.6 units in th... | PMID: 12492801

I and II adult patients with chronic sinutitis undergoing ESS were studied. All patients were not premedicated. Anesthesia was induced with propofol and maintained with sevoflurane and fentanyl. The patients were allocated randomly into two groups. In patients of Group C, mean arterial blood pressur... | PMID: 12428313

Hemodynamic instability in the polytraumatized patient is a predominant feature and most commonly secondary to blood loss accompanying injury. In these patients restoration of intravascular volume attempting to achieve normal systemic pressure faces the risk of increasing blood loss and thereby pote... | PMID: 12395169

Controlled hypotension during surgery was associated with a small but significant increase in pancreatitis-associated protein compared with controls. The absence of concomitant elevation in lipase concentrations and a lack of clinical evidence of pancreatitis damage suggest that hypotension induces... | PMID: 12200953

Increasing inspired oxygen concentrations might provide a simple and effective intervention to increase oxygen tension in tissues during controlled hypotension. To test this hypothesis, the influence of hyperoxic ventilation (100% O2) on skeletal muscle oxygen partial pressure (Ptio2) in patients rec... | PMID: 11981149

The bleeding was limited to 10 ml in 99 sides(69%), the mean bleeding amount was controlled to (18.7 +/- 24.4) ml in 78(54%) sides of patients with hypertension. In 66 sides (46%) of patients with normal blood pressure, the mean bleeding amount was (13.2 +/- 16.8) ml (P < 0.05). In 21 patients in wh... | PMID: 12768726

We evaluated the effects of prostaglandin E1 (PGE1) on the liver function and hemorrhage after total hip arthroplasty (THA). Twenty patients with normal liver function were randomly divided into two groups. The patients were anesthetized with spinal anesthesia using 0.5% bupivacaine 4 ml and epidura... | PMID: 11995344

We present preliminary clinical experience with the use of dexmedetomidine, an alpha2 adrenergic agonist, in children. Dexmedetomidine was administered in three clinical scenarios: (i) to provide sedation during mechanical ventilation; (ii) intraoperatively for controlled hypotension during an ortho... | PMID: 11882231

The use of profound induced hypotension to provide better operating conditions for surgery is long established. However, it is a controversial technique and it may be argued that it is inappropriate in modern anaesthetic practice. A currently used technique is reviewed against the benchmark of a law... | PMID: 11902095

In all, 150 sets of arterial pressures measurement were obtained. There were no statistically significant differences between radial and femoral arterial pressures measured before, during or after controlled hypotension. CONCLUSION: Radial arterial pressure is an accurate measure of central arterial... | PMID: 11942865

Due to the potential for the transmission of infectious diseases with the homologous transfusion of blood products, there has been an increased interest in measures to limit intraoperative blood loss and avoid the need for homologous transfusion during high-risk surgical procedures including spinal... | PMID: 12083972

A significant decrease in PaCO2 (7%) and ETCO2 (17%) from time 1 to time 2 (p < 0.01) was noted, as was a significant increase in P(a-ET)CO2 (48%) and in the Vdphys/Vt ratio (41.17%) (p < 0.01) during the same period. CONCLUSION: The decrease in ETCO2 does not reflect the changes in PaCO2. The large... | PMID: 12116693

Selected orthopedic surgical procedures, such as total joint arthroplasty and spinal instrumentation, have some of the highest perioperative transfusion rates of all surgical procedures. Blood transfusions carry the risk of complications, including the transmission of disease, immunomodulation, and... | PMID: 11832977
