Study on Dynamic Multimodal Analgesia Regimen Integrated With Traditional Chinese and Western Medicine After Perianal Abscess Surgery

2 augustus 2026 bijgewerkt door: The Affiliated Hospital of Putian University

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.

  4. Patients are willing and capable of participating in the pain management protocol, fully understand the significance of pain management, and can actively cooperate with study procedures;
  5. No severe coagulation disorders.

Exclusion Criteria:

  1. Complicated with specific infectious diseases such as Crohn's disease and tuberculosis;
  2. Unclear source of postoperative pain, i.e., the origin of pain cannot be confirmed or the pain is unrelated to surgery;
  3. Presence of definite contraindications, including drug allergy or inability to tolerate any pain management measures adopted in this trial;
  4. Pregnant or lactating women;
  5. Patients unable to cooperate with the study, such as those with cognitive impairment, history of mental illness, communication barriers and other conditions;
  6. Patients with long-term analgesic medication use and established drug tolerance;
  7. Complicated with uncontrolled cardiovascular and cerebrovascular diseases (NYHA cardiac function class Ⅲ-Ⅳ), hepatic and renal insufficiency (Child-Pugh class C or eGFR < 30 mL/min/1.73 m²), etc.;
  8. Abscess secondary to rectal neoplasms, trauma or iatrogenic injury;
  9. Severe postoperative complications (such as massive hemorrhage, sepsis) or concurrent infections at other sites;
  10. Patients receiving only non-surgical treatments such as simple needle aspiration of pus.

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Ander: Western Multimodal Analgesia Group
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.
Ander: TCM sitz bath
TCM sitz bath
Experimenteel: Integrated Traditional Chinese and Western Medicine Multimodal Analgesia Group
integrated Chinese-Western multimodal analgesia. 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

Wat meet het onderzoek?

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Numerical Rating Scale，NRS
Tijdsspanne: Postoperative days 1, 2, 3, 4, 5, 2 weeks and 1 month
The Numerical Rating Scale (NRS) for pain assessment ranges from 0 to 10, with higher scores indicating more severe pain and poorer outcomes.
Postoperative days 1, 2, 3, 4, 5, 2 weeks and 1 month
total postoperative analgesic consumption
Tijdsspanne: Postoperative days 1, 2, 3, 4, 5, 2 weeks and 1 month
Total consumption of analgesics was converted to morphine equivalent daily dose (MEDD) for intergroup comparison.
Postoperative days 1, 2, 3, 4, 5, 2 weeks and 1 month
postoperative quality of life indicators
Tijdsspanne: at day 3 and month 1 postoperatively
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.
at day 3 and month 1 postoperatively

Secundaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
postoperative urinary retention
Tijdsspanne: 24 hours postoperatively
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.
24 hours postoperatively
secondary hemorrhage
Tijdsspanne: 24 hours postoperatively
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.
24 hours postoperatively
perianal edema
Tijdsspanne: within 72 hours postoperatively
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.
within 72 hours postoperatively
assessment of sexual function
Tijdsspanne: assessed preoperatively and at 1 month postoperatively
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.
assessed preoperatively and at 1 month postoperatively
