Increasing the IV fluids during surgery by giving additional fluid while the person is under general anaesthesia may reduce the risk of nausea/vomiting after surgery. [1] For minor surgical procedures, more research is needed to determine the risks and benefits of this approach.
During open surgery the surgeon exposes the peritoneal cavity to the ambient air. Exposure to ambient air results in evaporation and cooling. Current studies have shown that the use of surgical humidification during open abdominal surgery (laparotomy) have warmer core body temperatures and reduced risk of operative hypothermia.
Gases are often insufflated into a body cavity to inflate the cavity for more workroom, e.g. during laparoscopic surgery. The most common gas used in this manner is carbon dioxide, because it is non-flammable, colorless, and dissolves readily in blood.
Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity.The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
The gas is a mixture of half nitrous oxide (N 2 O) and half oxygen (O 2). [ 1 ] [ 23 ] The ability to combine N 2 O and oxygen at high pressure while remaining in the gaseous form is caused by the Poynting effect (after John Henry Poynting , an English physicist).
For uncomplicated laparoscopic cholecystectomies, people may be discharged on the day of surgery after adequate control of pain and nausea. [41] Patients who were high-risk, those who required emergency surgery, and/or those undergoing open cholecystectomy usually need to stay in the hospital several days after surgery. [21]

Disposable trocars Laparoscopic instruments for insertion through trocars. A trocar (or trochar) is a medical or veterinary device used in minimally invasive surgery.Trocars are typically made up of an awl (which may be metal or plastic with a pointed or tapered tip), a cannula (essentially a rigid hollow tube) and often a seal.
