To compare results for body (esophageal) temperature measurements obtained during celiotomy in normothermic (presurgical) canine patients receiving routine heat support versus routine heat support plus supplemental support (consisting of covering the thorax in a reflective blanket and placing reflective blankets plus wool socks on 3 limbs) in a prospective randomized controlled clinical trial.
44 dogs requiring celiotomy that were presented sequentially to an emergency and specialty referral veterinary hospital.
The 44 dogs undergoing celiotomy were randomly assigned to 2 groups. The control group received routine intraoperative heat support consisting of a circulating warm water blanket and either a towel or blanket. The supplemental group received the same routine heat support plus a reflective blanket covering the cervical and thoracic regions and reflective blankets wrapped around 3 limbs and covered with wool socks from the digits to the axillary or inguinal region.
Mean esophageal temperature for both the control and supplemental groups dropped throughout celiotomy. Esophageal temperature measurements at several time points were significantly higher for the supplemental group than for the control group. The lowest temperature measurement for the supplemental group, adjusted for initial esophageal temperature and procedure duration, was significantly higher by 0.8 °C than that for the control group.
Covering the cervical and thoracic regions with a reflective blanket and wrapping limbs in reflective blankets and wool socks is an affordable adjunctive method to provide passive heat support and minimize perioperative hypothermia in canine patients undergoing celiotomy.
在一项前瞻性随机对照临床试验中,比较接受常规热支持(围手术期)的正常体温(术前)犬患者与接受常规热支持加补充支持(包括用反射毯子覆盖胸部和在 3 个肢体上放置反射毯子和羊毛袜子)的剖腹手术犬患者的体(食管)温测量结果。
44 只需要剖腹手术的犬,连续送到急诊和专科转诊兽医医院。
接受剖腹手术的 44 只犬被随机分配到 2 组。对照组接受常规术中热支持,包括循环温水毯和毛巾或毯子。补充组接受相同的常规热支持,外加覆盖颈部和胸部的反射毯子,以及包裹在 3 个肢体上的反射毯子,并从指端到腋窝或腹股沟区域覆盖羊毛袜子。
对照组和补充组的平均食管温度在整个剖腹手术过程中均下降。在几个时间点,补充组的食管温度测量值明显高于对照组。调整初始食管温度和手术持续时间后,补充组的最低温度测量值比对照组高 0.8°C。
用反射毯子覆盖颈部和胸部区域,并用反射毯子和羊毛袜子包裹肢体,是一种经济实惠的辅助方法,可以为接受剖腹手术的犬患者提供被动热支持,并最大限度地减少围手术期低体温。
