Perianal AbscessNCT07744594
Study on Dynamic Multimodal Analgesia Regimen Integrated With Traditional Chinese and Western Medicine After Perianal Abscess Surgery
A study testing TCM sitz bath in people with Perianal Abscess, run by The Affiliated Hospital of Putian University at 1 site in China.
Trial summary
Background:Perianal abscess is a common acute anorectal pyogenic disease (8%-25% of anorectal illnesses), mainly seen in men aged 20-40. Over 90% suffer severe postoperative pain, impairing healing, triggering anxiety or sepsis and raising medical loads. Read more about this study

About this study
Official title: Study on Dynamic Multimodal Analgesia Regimen Integrated With Traditional Chinese and Western Medicine After Perianal Abscess Surgery: A Single-Center, Prospective, Open-Label Randomized Clinical Trial
Background:Perianal abscess is a common acute anorectal pyogenic disease (8%-25% of anorectal illnesses), mainly seen in men aged 20-40. Over 90% suffer severe postoperative pain, impairing healing, triggering anxiety or sepsis and raising medical loads. Western multimodal analgesia eases pain yet causes dependence and side effects. TCM sitz baths clear heat, reduce swelling and promote recovery. Few personalized combined protocols are available, and integrated Chinese-Western synergies are insufficiently exploited. This optimized integrated intervention guides postoperative pain nursing.

| Study group | Role | What they receive |
|---|---|---|
| Western Multimodal Analgesia Group | Other | Western multimodal analgesia. Dynamic whole-course NRS evaluation was performed: baseline measurement preoperatively, regular rest/activity pain checks and breakthrough pain assessment postoperatively, plus follow-up reassessment after discharge. Stepwise stratified medication was applied alongside non-pharmacological measures including potassium permanganate sitz bath, health education and psychological counseling. A pain management team adjusted regimens individually via daily ward rounds. Receives: Other: TCM sitz bath |

All interventions of Group B were adopted, with additional TCM sitz bath and TCM nursing; assessment and Western medicine protocols remained identical to Western Multimodal Analgesia Group Receives: Other: TCM sitz bath |
What is being measured
The primary outcome is the main question the study is designed to answer.
Numerical Rating Scale，NRS
The Numerical Rating Scale (NRS) for pain assessment ranges from 0 to 10, with higher scores indicating more severe pain and poorer outcomes.
Measured: Postoperative days 1, 2, 3, 4, 5, 2 weeks and 1 month
total postoperative analgesic consumption
Total consumption of analgesics was converted to morphine equivalent daily dose (MEDD) for intergroup comparison.
Measured: Postoperative days 1, 2, 3, 4, 5, 2 weeks and 1 month
postoperative quality of life indicators
The Short-Form 36 (SF-36) Health Survey was employed to evaluate quality of life, with each domain scored from 0 (minimum) to 100 (maximum), and higher scores reflecting more favorable health status and better quality of life.
Measured: at day 3 and month 1 postoperatively
Secondary outcomes (4)
postoperative urinary retention
Patients were placed in the supine position with a moderately full bladder. The ultrasound probe was positioned above the pubic symphysis, and the anteroposterior, transverse, and longitudinal diameters of the bladder were measured. The post-void residual urine volume was calculated using the formula: bladder volume (mL) ≈ 0.52 × length × width × height (cm). A residual volume of <50 mL was considered normal, 50-200 mL indicated mild urinary retention or impaired voiding, and >200 mL was diagnostic of postoperative urinary retention. Complete inability to void with a bladder volume of >400 mL was defined as acute urinary retention.
Measured: 24 hours postoperatively
secondary hemorrhage
Active oozing from the surgical wound occurring beyond 24 hours postoperatively, with a blood loss of ≥5 mL, requiring dressing change and continuous compression hemostasis with sterile gauze; secondary suturing is indicated if bleeding cannot be controlled.
Measured: 24 hours postoperatively
perianal edema
Perianal edema was defined as visible significant soft-tissue swelling around the operative site, accompanied by local tenderness, with the edema persisting for more than 72 hours.
Measured: within 72 hours postoperatively
assessment of sexual function
Erectile function in male patients was evaluated using the International Index of Erectile Function-5 (IIEF-5), which has a total score ranging from 5 (minimum) to 25 (maximum), with higher scores denoting better erectile function. For female patients, sexual function was assessed using the Female Sexual Function Index (FSFI), with total scores ranging from 2 to 36, where a higher score indicates better sexual function.
Measured: assessed preoperatively and at 1 month postoperatively
