“…Hypothermia has also been associated with wound infection [5], shivering [6], perioperative cardiac events [7], and prolonged recovery and hospitalization [8]. Therefore, many strategies have been devised to prevent intraoperative hypothermia, e.g., a forced-air warming system [9], fluid warmers [10], circulating-water mattresses [11], and insulation of the skin surface [12]. …”

BackgroundGeneral anesthesia often produces some degree of hypothermia and hypothermia causes much more blood loss during surgery than normothermia. Electrically heated humidifiers (EHHs) have been used for patients under general anesthesia and in the intensive care unit. However, the benefits of the EHH have not been widely reported in the literature.MethodsPatients scheduled for posterior lumbar spine fusion, were randomly assigned to a mechanically ventilated with EHH circuit group or to a conventional respiratory circuit group. Their tympanic membrane temperature was monitored every 30 min after induction up to 180 min, and perioperative blood losses, transfusion requirements during surgery, and other complications were noted.ResultsPatients in the control group (n = 40) showed a lower mean body temperature at all times than immediately after induction, while the EHH group (n = 40) showed a lower body temperature from 60 minute after induction comparing to the initial temperature. Furthermore, patients in the EHH group had a higher mean body temperature than patients in the control group during surgery (35.9 ± 0.4 vs 35.4 ± 0.5, P < 0.001). Mean intraoperative blood loss (9.75 ± 5.4 vs 7.48 ± 3.9, P = 0.035) and transfusion requirements (57.5% vs 25%, P = 0.006) were significantly less in the EHH group, but postoperative blood loss, duration of hospitalization, and other complications were not significantly different in the two study groups.ConclusionsThe use of an electrically heated humidifier did not prevent a body temperature drop under general anesthesia. However, it helped maintain body temperature and was associated less blood loss and transfusion requirement during surgery.

“…In addition, considering that the thorax is opened and the extremities are exposed for vessel harvesting, the surface area of the body for heat dispersion is high. [92] Once the patient becomes hypothermic it may be difficult to increase the core temperature until after surgery and the risk of complications increases. [93,94] In order to maintain temperature homeostasis fluid warming is useful.…”

Anesthesia for off-pump coronary artery bypass surgery

The evolution of techniques and knowledge of beating heart surgery has led anesthesia toward the development of new procedures and innovations to promote patient safety and ensure high standards of care. Off-pump coronary artery bypass (OPCAB) surgery has shown to have some advantages compared to on-pump cardiac surgery, particularly the reduction of postoperative complications including systemic inflammation, myocardial injury, and cerebral injury. Minimally invasive surgery for single vessel OPCAB through a limited thoracotomy incision can offer the advantage of further reduction of complications. The anesthesiologist has to deal with different issues, including hemodynamic instability and myocardial ischemia during aorto-coronary bypass grafting. The anesthesiologist and surgeon should collaborate and plan the best perioperative strategy to provide optimal care and ensure a rapid and complete recovery. The use of high thoracic epidural analgesia and fast-track anesthesia offers particular benefits in beating heart surgery. The excellent analgesia, the ability to reduce myocardial oxygen consumption, and the good hemodynamic stability make high thoracic epidural analgesia an interesting technique. New scenarios are entering in cardiac anesthesia: ultra-fast-track anesthesia with extubation in the operating room and awake surgery tend to be less invasive, but can only be performed on selected patients.

“…Conduction and evaporation account for less than 15% of total heat loss 4 . Conduction is the process of heat loss via physical contact with another object or body (eg, the OR bed mattress) 5 . Evaporation is the process of losing heat through the conversion of water to gas (eg, evaporation of sweat).…”

Hypothermia is one of the most common complications experienced by surgical patients. Better postoperative patient outcomes are achieved when normothermia is maintained. Perioperative nurses should understand how to maintain normothermia, the causes of hypothermia, and adverse patient outcomes that result from hypothermia. Nursing interventions to help prevent hypothermia can be implemented during each phase of perioperative care.
