Objective

To collect baseline descriptive data on the anaesthesia and analgesia protocols used by New Zealand veterinarians in first-opinion practice when performing routine canine and feline ovariohysterectomies.

Study design

Cross-sectional survey.

Animals

Not applicable.

Methods

An online survey was conducted asking respondents for: 1) preoperative patient assessment; 2) preanaesthetic medication and induction drugs used; 3) anaesthesia maintenance drug choices and monitoring equipment used; and 4) postoperative analgesia drug selections and monitoring for ovariohysterectomy performed in healthy adult dogs and cats.

Results

The survey was completed by 472 veterinarians, of whom 282 provided responses for canine ovariohysterectomy and 361 provided responses for feline ovariohysterectomy. Approximately 23% of canine ovariohysterectomies and 13% of feline ovariohysterectomies had preanaesthetic bloodwork performed. There were 74 unique premedication/induction drug combinations reported for canine ovariohysterectomies and 94 for feline ovariohysterectomies. The most commonly used drug combinations were acepromazine, morphine ± propofol and butorphanol, ketamine and medetomidine for canine and feline ovariohysterectomies respectively. Most animals were intubated, and anaesthesia was maintained with isoflurane in oxygen. Use of intravenous catheters, fluid administration, heat support, and monitoring equipment varied. There were 41 unique postoperative analgesia drug combinations reported for canine ovariohysterectomies and 20 for feline ovariohysterectomies. Canine ovariohysterectomies were most commonly administered injectable opioids on the day of surgery followed by 3 days of oral non-steroidal anti-inflammatory drugs (NSAIDs), whereas feline ovariohysterectomies were usually administered a single injection of an opioid or NSAID or both on the day of surgery. Most animals were seen within 7–10 days for re-examination and/or suture removal.

Conclusions and clinical relevance

Veterinarians use a wide range of anaesthesia and analgesia protocols for routine ovariohysterectomies. Further research is needed comparing the safety and efficacy of commonly used protocols to determine whether there are opportunities to improve the level of patient welfare.

用于执行常规犬和猫卵巢子宫切除术的麻醉和镇痛方案的横断面调查。

目的

收集常规操作犬和猫卵巢输卵管切除术时新西兰兽医在初次实践中使用的麻醉和镇痛方法的基准描述性数据。

学习规划

横断面调查。

动物

不适用。

方法

进行了一项在线调查，要求受访者提供：1）术前患者评估；2）所使用的麻醉前药物和诱导药物；3）麻醉维持药物的选择和使用的监测设备；4）在健康的成年犬和猫中进行术后镇痛药物的选择和卵巢子宫切除术的监测。

结果

该调查由472位兽医完成，其中282位提供了犬卵巢子宫子宫切除术的响应，而361位提供了对猫卵巢子宫子宫切除术的响应。大约23％的犬卵巢输卵管子宫切除术和13％的猫卵巢输卵管子宫切除术进行了麻醉前的血液检查。据报道，犬卵巢输卵管子宫切除术有74种独特的用药/诱导药物组合，而猫卵巢输卵管子宫切除术有94种。最常用的药物组合分别是醋丙嗪，吗啡±丙泊酚和丁啡诺，氯胺酮和美托咪定分别用于犬和猫卵巢子宫切除术。对大多数动物进行插管，并在氧气中用异氟烷维持麻醉。静脉导管的使用，输液，热支持和监测设备各不相同。据报道，犬卵巢输卵管子宫切除术有41种独特的术后镇痛药物组合，猫卵巢输卵管子宫切除术有20种独特的镇痛药物组合。犬卵巢输卵管子宫切除术最常用的是手术当天的可注射阿片类药物，然后是3天口服非甾体类抗炎药（NSAIDs），而猫卵巢输卵管子宫切除术通常在手术当天使用阿片类药物或NSAID或两者同时注射手术。在7-10天内可以看到大多数动物进行复检和/或缝合线去除。而猫卵巢子宫切除术通常在手术当天单次注射阿片样物质或非甾体抗炎药或两者同时给药。在7-10天内可以看到大多数动物进行复检和/或缝合线去除。而猫卵巢子宫切除术通常在手术当天单次注射阿片样物质或非甾体抗炎药或两者同时注射。在7-10天内可以看到大多数动物进行复检和/或缝合线去除。

结论与临床意义

兽医对常规的卵巢子宫切除术使用广泛的麻醉和镇痛方案。需要进行进一步的研究，比较常用方案的安全性和有效性，以确定是否有机会提高患者福利水平。
