“…After three to five hours of anesthesia, the decrease in core temperature reportedly ceases with the emergence of thermoregulatory vasoconstriction (1). In addition to intraoperative factors (3, 6, 17), preoperative factors including age (6–8), body fat mass (9, 10), preoperative medication (12, 16, 18), gender (19), and diabetic neuropathy (20) are known to affect thermoregulation during general anesthesia. Accordingly, we recruited sex‐ and age‐matched patients, who had no history of diabetes mellitus, had received no premedication and whose % body fat values were the same between the two groups in this study.…”

“…7 Another study implicated the relationship of the renin-angiotensin system on peripheral vasoconstriction and thermoregulation. 8 But, to our knowledge, there is no study demonstrating the effect of body temperature on PVP and its agreement with CVP. In this study, we aimed to investigate the effect of passively occurring peripheral (Tp) and core (Tc) body temperature changes on PVP and the agreement with CVP in patients undergoing intracranial surgery under general anesthesia.…”

Previous studies suggest a correlation of central venous pressure (CVP) with peripheral venous pressure (PVP) in different clinical settings. The effect of body temperature on PVP and its agreement with CVP in patients under general anesthesia are investigated in this study. Fifteen American Society of Anesthesiologists I-II patients undergoing elective craniotomy were included in the study. CVP, PVP, and core (Tc) and peripheral (Tp) temperatures were monitored throughout the study. A total of 950 simultaneous measurements of CVP, PVP, Tc, and Tp from 15 subjects were recorded at 5-minute intervals. The measurements were divided into low- and high-Tc and -Tp groups by medians as cutoff points. Bland-Altman assessment for agreement was used for CVP and PVP in all groups. PVP measurements were within range of +/-2 mm Hg of CVP values in 94% of the measurements. Considering all measurements, mean bias was 0.064 mm Hg (95% confidence interval -0.018-0.146). Corrected bias for repeated measurements was 0.173 +/- 3.567 mm Hg (mean +/- SD(corrected)). All of the measurements were within mean +/- 2 SD of bias, which means that PVP and CVP are interchangeable in our setting. As all the measurements were within 1 SD of bias when Tc was > or = 35.8 degrees C, even a better agreement of PVP and CVP was evident. The effect of peripheral hypothermia was not as prominent as core hypothermia. PVP measurement may be a noninvasive alternative for estimating CVP. Body temperature affects the agreement of CVP and PVP, which deteriorates at lower temperatures.

“…A 6-degree head-down tilt position during surgery induces fluid shift from the lower to the upper body, along with cardiopulmonary baroreceptor reflex responses including bradycardia, an increase in urinary excretion of sodium, and thermoregulatory changes [ 1 , 2 ]. In addition to these physiological responses, a steep 25–40-degree head-down tilt position during robot-assisted laparoscopic prostatectomy (RALP) may cause postoperative laryngeal edema [ 3 ].…”

Background Preoperative vocal cord paralysis is a risk factor for postoperative respiratory distress following extubation after general anesthesia. We present an unusual case where a geriatric patient developed airway obstruction after robot-assisted laparoscopic prostatectomy. Case Presentation A 67-year-old male, who had suffered from left vocal cord paralysis of unknown etiology, was scheduled for robot-assisted laparoscopic prostatectomy (RALP). General anesthesia was performed without any problems. The patient, however, developed airway obstruction one hour after extubation and was reintubated following commencement of mechanical ventilation for one day. At the age of 70 years, the patient received an emergency tracheostomy due to bilateral vocal cord paralysis and then was diagnosed with spinal and bulbar muscular atrophy (SBMA). Although no muscle weakness of either upper or lower extremities was observed, rocuronium showed hypersensitivity during total laryngectomy under general anesthesia. Conclusions Vocal cord paralysis combined with postoperative laryngeal edema, the cause of which was presumed to be SBMA, likely caused airway obstruction after RALP. As neuromuscular symptoms progress gradually in patients with SBMA, muscle relaxants should be used carefully, even if patients with SBMA present no immobility of their extremities.

Thermoregulatory response in female patients during lower abdominal surgery in the head‐down tilt position

Abstract: During lower abdominal surgery the head-down tilt position does not augment core hypothermia in spite of suppressed peripheral vasoconstriction, and the renin-angiotensin system may be of importance for thermoregulation.
