Transoesophageal echocardiographic assessment of haemodynamic function during laparoscopic cholecystectomy.
We have measured cardiovascular changes associated with insufflation of carbon dioxide and the reverse Trendelenburg position during laparoscopic cholecystectomy, using transoesophageal
The relationship between "normal" transesophageal color-flow Doppler-defined tricuspid regurgitation and thermodilution right ventricular ejection fraction measurements.
Twenty coronary artery revascularization patients, aged 58 +/- 15 years, were studied intraoperatively to define the impact of Doppler-defined tricuspid regurgitation on measurement of thermodilution
Perioperative considerations in the management of tracheotomy for the obstructive sleep apnoea patient. Three illustrative case reports.
The perioperative course of three patients with obstructive sleep apnoea who underwent tracheotomy is presented as illustrative of the potentially life-threatening complications of management. It is
The effect of high frequency positive pressure ventilation on right and left ventricular function.
The data suggest that cardiac function declines linearly as driving pressure increases during HFPPV, and that in conditions of acute lung injury requiring DP >30 psi, H FPPV affords no cardiorespiratory advantage over IPPV.
Transesophageal two-dimensional echocardiographic analysis of right ventricular systolic performance indices during coronary artery bypass grafting.
Sixteen patients undergoing coronary artery bypass surgery were evaluated to delineate the intraoperative course of transesophageal echocardiographic right ventricular (RV) systolic performance indices and CPB was associated with significant decreases in max major axisLA and 2DLA (P < 0.05) as compared to measurements determined prior to CPB.
Patent foramen ovale and paradoxical embolization: a historical perspective.
The use of transesophageal echocardiography for intraoperative management of critically ill patients allows for routine evaluation of foramen ovale patency, and earliest documentation of paradoxical embolization through a patent foramen Ovale is researched as a historical issue with present day relevance.
A metropolitan experience with infrainguinal revascularization. Operative risk and late results in northeastern Ohio.
Although both materials had similar success above the knee, the cumulative 3-year patency rate of autogenous vein bypass to the distal popliteal was superior to the results of polytetrafluoroethylene grafts, which required reoperation at three times the rate of vein grafts to maintain limb salvage.
Hemodynamics in patients with severe toxemia during labor and delivery.
Three patients with severe pre-eclampsia-toxemia were studied with thermodilution tip pulmonary artery catheters and Pulmonary arteriolar resistance was found to be within or below the normal nonpregnant range, suggesting that in severe toxemia the pulmonary vasculature is not involved in a primary vasospastic process.
Transcutaneous Po2 as a Trend Indicator of Arterial Po2 in Normal Anesthetized Adults
The transcutaneous technique of measuring Po2 (tcPo2) was studied in 30 adults with normal cardiovascular function undergoing nitrous oxide-enflurane or nitrous oxide-fentanyl anesthesia to determine
Relationship between Transcutaneous and Arterial Carbon Dioxide Tension in Adult Patients Anesthetized with Nitrous Oxide‐Fentanyl and Nitrous Oxide‐Enflurane
The transcutaneous technique of measuring carbon dioxide tension (tcPCO2) was studied in 30 adult neurosurgery patients undergoing nitrous oxide-enflurane or nitiss oxide-fentanyl anesthesia and was an accurate and clinically useful trend indicator of PaCO2.
