Question

Quizplus · Accepted Answer

The surgeon makes a paraumbilical incision and inserts an insufflation (Veress)needle into the abdomen.After needle confirmation,insufflation tubing is connected and the process begun.CO₂ gas is used to insufflate because it does not support combustion,can be absorbed at large volumes per minute without serious side effects,and is fairly inexpensive.The peritoneal cavity is filled,first at a low flow rate that is increased to a high flow rate of at least 9 L/min ideally.Flow rate refers only to how quickly a predetermined intra-abdominal pressure can be reached.Intra-abdominal pressure is the actual measure that must be closely monitored and should be maintained between 14 and 16 mm Hg.
