Clinical Significance And Effect Of Temperature Protection For Body Temperature And Lactate Of Neurosurgical Patients

Objective: To discuss the effects of temperature protection on the lacticcontent of neurosurgery patients body temperature and jugular bulb bloodoxygen saturationMethods: Select40cases, randomly divided into two groups: experimentalgroup and the control group,20cases in each group. All the selected patients,ASAâ… -â…¡ level, no serious liver and kidney dysfunction, no endocrine systemdisease. The patients in experimental group, all intraoperative liquids are heated,37℃，including intravenous fluids and rinse solution. The patients in this groupuse warm temperature blanket, which set for37℃, and the patient’s body iscovered with a thin blanket. The patients in control group use the normaltemperature liquid, no warm blankets or a thin blanket. Routine anesthesiainduction, Propofol and Fentanyl with Cisatracurium maintain anesthesia.Choose no intraoperative blood transfusion cases, no using intraoperativecontrolled hypotension. In intubation immediate （T₁）, induced60min （T₂）,120min （T₃）,180min （T₄）, surgery completed （T₅）, to observe the nasopharyngealtemperature, blood lactic acid （AL）, jugular bulb venous blood lactic acid（VL）, internal bulb jugular blood oxygen saturation （SjvO₂）, blood loss, urinevolume, and the transfusion volume. The length of ICU stay，ventilation time and vasoactive agent and alkaline drug use were compared between two groups.The recovery of patients and variation tendency of arterial blood lacticacid, pHand base excess （BE） were observed.Results:1. In T₃and later each time point, the nasopharyngealtemperature of the experimental group is higher than that of the control group,which had statistical significance （P<0.05）; In the experimental group,compared to T₂time point temperature, the nasopharyngeal temperaturechanges in T₂and later each time point are not obvious, which had nostatistical significance （P>0.05）.2. In the control group, T₃and later eachtime point, AL, ADVL values were distinctly higher than T₁, which hadstatistical significance （P<0.05）; In control group, AL, ADVL values in T₃and later each time point are higher than the experimental group in the sametime point, which had statistical significance （P<0.05）.3. SjvO₂in T₄, T5timepoints of experimental group was significantly higher than the control groupin the same time point, there is statistical significance （P<0.05）; In the controlgroup, SjvO₂values in T₂and later each time points are lower than T₁, whichhad statistical significance （P<0.05）.4.The experimental group compared tothe control group, mechanical ventilation time was shorter, ICU stay time wasshorter, the basic drug use frequency was lower, which had statisticalsignificance （P<0.05）. Postoperative pH and BE had larger fluctuation range.Conclusion: Temperature protection help to keep constant bodytemperature of neurosurgical patients, to reduce the production of lactic, to maintain the balance of brain tissue oxygen supply and oxygen demand, andis conducive to the neurosurgery patients with postoperative recovery.
