Cardiovascular effects of peritoneal insufflation of carbon dioxide for laparoscopy.
We have investigated, in 13 artificially ventilated and anaesthetized patients, the cardiovascular effects of peritoneal insufflation of carbon dioxide preparatory to laparoscopy. Stepwise increases of intra-abdominal pressure up to a maximum of 25 cm H(2)O were accompanied by increases of airway pressure, intrathoracic pressure, central venous pressure, and femoral venous pressure and by signs...
متن کاملEquipment review: Tracheal gas insufflation
47cc-2-2-043 Introduction Tracheal gas insufflation (TGI) is an adjunctive ventilatory technique that delivers fresh gas into the trachea either continuosly or only during a specific segment of the respiratory cycle (phasic flow) [1-4]. Two mechanisms are responsible for improving the efficacy of conventional tidal breaths during TGI [5-7]. First, fresh gas introduced by the catheter during exp...
متن کاملDistal projection of insufflated gas during tracheal gas insufflation.
Tracheal gas insufflation (TGI) flushes expired gas from the ventilator circuitry and central airways, augmenting CO2 clearance. Whereas a significant portion of this washout effect may occur distal to the injection orifice, the penetration and mixing behavior of TGI gas has not been studied experimentally. We examined the behavior of 100% oxygen TGI injected at set flow rates of 1-20 l/min int...
متن کاملMonitoring and humidification during tracheal gas insufflation.
In order to use tracheal gas insufflation (TGI) in a safe and effective manner, it is important to understand potential interactions between TGI and the mechanical ventilator that may impact upon gas delivery and carbon dioxide (CO2) elimination. Furthermore, potentially serious complications secondary to insufflation of cool, dry gas directly into the airway and the possibility of tube occlusi...
متن کاملCirculatory effects of carbon dioxide insufflation of the peritoneal cavity for laparoscopy.
Measurements of cardiac output, mean arterial pressure, central venous pressure, and heart rate were made in seven patients undergoing laparoscopy. Measurements were made before and after insufflation of the peritoneum with carbon dioxide, and again after intravenous injection of oxprenolol 2 mg. No significant change in cardiac output followed peritoneal insufflation, but there was a significa...
