An important argument for emergency physician use of ultrasonography is that it results in more rapid patient disposition, but there are few articles to support this position. This study sought to demonstrate a significant decrease in the time spent in the ED when emergency physicians performed transvaginal ultrasonography (TVUS), as compared with when TVUS was performed by consultants, in the evaluation of first-trimester pelvic pain or vaginal bleeding.
A retrospective analysis was conducted of the time spent in the ED (time placed in gynecologic examination room to time released from ED) by patients with first-trimester pelvic pain or vaginal bleeding necessitating further evaluation with TVUS. TVUS was performed in the ED by obstetrics/gynecology (ob/gyn) residents who were consulted to the ED from January 11, 1996, to March 31, 1996, and by emergency physicians from April 17, 1996, to July 7, 1996.
Emergency physicians evaluated 46 patients by TVUS, with a mean time of 164.70 minutes (SEM +/- 13.29). Ob/gyn consultants evaluated 38 patients by TVUS, with a mean time of 234.79 minutes (SEM +/- 12.74). This was a significant difference at the level of p < 0.0003 (Student's t-test). There were no known missed ectopic pregnancies as ascertained by 100% patient follow-up. There was no significant difference between the groups in the percentage of ectopic pregnancies (Fisher's exact test). The number of patients in the emergency physician group requiring subsequent consultation was reduced by 85%.
This study demonstrates a more rapid ED transit time when TVUS was performed at the bedside by emergency physicians as compared with when pelvic ultrasonography required consultation. Additionally, fewer calls to consultants were required.
急诊医生使用超声检查的一个重要论据是它能使患者更快地得到处置,但支持这一观点的文章很少。本研究旨在证明,在评估孕早期盆腔疼痛或阴道出血时,与由会诊医生进行经阴道超声检查(TVUS)相比,急诊医生进行TVUS时,患者在急诊科停留的时间显著缩短。
对因孕早期盆腔疼痛或阴道出血而需要通过TVUS进一步评估的患者在急诊科停留的时间(从进入妇科检查室到离开急诊科的时间)进行回顾性分析。TVUS由1996年1月11日至1996年3月31日被会诊到急诊科的妇产科住院医师,以及1996年4月17日至1996年7月7日的急诊医生在急诊科进行。
急诊医生通过TVUS评估了46例患者,平均时间为164.70分钟(标准误±13.29)。妇产科会诊医生通过TVUS评估了38例患者,平均时间为234.79分钟(标准误±12.74)。在p<0.0003水平上,这是一个显著差异(学生t检验)。通过100%的患者随访确定,没有已知的异位妊娠漏诊情况。两组之间异位妊娠的百分比没有显著差异(Fisher精确检验)。急诊医生组中需要后续会诊的患者数量减少了85%。
本研究表明,与需要会诊的盆腔超声检查相比,急诊医生在床边进行TVUS时,患者在急诊科的周转时间更快。此外,需要会诊医生的次数也更少。
