new YORK, 23 mar (Reuters) – hypothermia
intraoperative of less than 35 degrees Celsius increases more than the
double the risk of infections in the area of the operation then
of a laparotomy for trauma, according to a report
published in Annals of Surgery.
“our results suggest that the normothermia
“
intraoperative should be kept strictly in the
patients who undergo surgical procedures by
“
trauma”, concluded the team doctor Mark j. Seamon, of the
Cooper University hospital in Camden, New Jersey.
Experts pointed out that the intraoperative normothermia is
one measure of quality established in Colorectal, surgery
but who have not studied their effects on the rate of
infection in the surgical area after laparotomy for
trauma.
To investigate the issue, the team reviewed the results of
524 patients who survived at least four days after
traumatic emergency laparotomy, including 189 to
developed wound infections.
The intraoperative average lowest temperature ever was 35.2
degrees Celsius and a 30.5 per cent had at least one measurement
below 35 degrees, the more predictive point of infection in
the wound.
After controlling for factors that could cause confusion,
the authors found that for each degree below 35 degrees
Celsius, the risk of infection in the wound site
increased by 221 percent.
The experts explained that hypothermia shoots the
cutaneous vasoconstriction, which leads to relative hypoxia of the
wound, and this sometimes affects the defense mechanisms of the
host.
El doctor Seamon and his colleagues pointed out that maintaining the
warm temperature during the operation demonstrated to reduce the
risk of infection in the wound after general surgery
head and neck or cardiothoracic, and also after a
cholecystectomy and open abdominal surgery.
“as far as I know, this is the first report that involves
“
intraoperative hypothermia in the development of infection in
“
the wound after laparotomy for trauma”,
indicated investigators.
“our data suggest that measures to keep the
“
temperature during the operation will help to prevent the
infection in the wound area and improve the results
“
after laparotomy for trauma”, advised the team.
