输注异丙酚预防术后恶心和呕吐 (PONV)
2026年8月11日 更新者:Revati Kanekar、Milton S. Hershey Medical Center
本研究的目的是阐明低剂量异丙酚输注是否可以有效预防有 PONV 和/或晕动病史的患者术后恶心呕吐 (PONV)。
研究概览
详细说明
对于有 PONV 和/或晕动病史的患者,异丙酚既可作为低剂量麻醉剂,也可作为唯一麻醉剂。
但尚未研究一种剂量相对于另一种剂量的功效。
本研究计划澄清对于有 PONV 和/或晕动病史的患者,低剂量异丙酚是否与作为单一麻醉剂一样有效

有源比较器:Hybrid anesthesia (propofol + sevoflurane)
Participants received general anesthesia maintained with a continuous low-dose propofol infusion combined with sevoflurane.
Anesthetic depth was titrated to a bispectral index (BIS) target of 40-60.
Standardized induction agents and prophylactic antiemetics were administered.

Number of Subjects Experiencing Post-Operative Nausea/Vomiting (PONV)
大体时间:24 hours
|
Postoperative nausea and vomiting (PONV) within 24 hours was defined as any episode of nausea, retching, or vomiting occurring from PACU discharge up to 24 hours after surgery.
Data were collected using standardized patient questionnaires and follow-up telephone interviews conducted at 24 hours after surgery.

Episodes of Post Operative Nausea/Vomiting (PONV)
大体时间:PACU
|
PONV in the post-anesthesia care unit (PACU) was defined as any episode of nausea, retching, or vomiting occurring between PACU admission and discharge.
Events were documented by PACU nursing staff as part of routine postoperative care.

Use of Antiemetics
大体时间:24 hours
|
Use of rescue antiemetics was defined as administration of any antiemetic medication beyond standardized prophylaxis (dexamethasone and ondansetron), either during the post-anesthesia care unit (PACU) stay or within 24 hours after surgery.
Antiemetic use was obtained from the medical record in the PACU and from patient self-report during standardized follow-up at 24 hours postoperatively.
The outcome was analyzed as a categorical variable and reported as the number and percentage of participants requiring rescue antiemetics.
