Evaluation of the nursing effect of mirabilite fomentation on postoperative edema, pain, and urinary retention in patients with mixed hemorrhoids

Q: What nursing effect does mirabilite fomentation aim to improve after surgery for mixed hemorrhoids?

It targets postoperative edema, pain, distension sensation, and urinary retention, alongside related outcomes such as wound healing and overall efficacy.

Q: How was the study designed and how were groups compared?

A retrospective cohort study enrolled 121 patients treated from January 2023 to December 2024. Propensity score matching was used to control confounding, yielding 72 comparable cases (36 per group).

Q: What were the key results regarding urinary retention and recovery?

Urinary retention occurred less often in the mirabilite group (11.1% vs 30.6%), time to first urination was shorter, wound healing time decreased, and patient satisfaction was higher, with no severe adverse reactions reported.

Study examines nursing outcomes of single-agent mirabilite fomentation after surgery for circumferential mixed hemorrhoids. A retrospective cohort of 121 patients treated with external stripping and internal ligation (Jan 2023–Dec 2024) was analyzed using propensity score matching to balance confounders, producing 72 comparable cases. Compared with controls, the mirabilite group showed lower postoperative bleeding scores, greater reductions in edema area and height, and more pronounced decreases in distension sensation and VAS pain over time. Urinary retention incidence decreased (11.1% vs 30.6%), time to first urination shortened, wound healing accelerated, overall efficacy increased, no severe adverse reactions occurred, and patient satisfaction improved.

This study aims to investigate the nursing effect of single-agent mirabilite fomentation on postoperative edema, pain, and urinary retention in patients with circumferential mixed hemorrhoids. A retrospective cohort study was conducted including 121 patients who underwent external stripping and internal ligation for circumferential mixed hemorrhoids in our hospital from January 2023 to December 2024. Patients were divided into a mirabilite fomentation group and a control group according to postoperative nursing methods. Propensity score matching was applied to control confounding factors, yielding 72 comparable cases (36 in each group) . Observational indicators included postoperative bleeding, anal margin edema, sensation of distension, pain (visual analogue scale), urinary retention and time to first urination, wound healing time, overall efficacy, adverse reactions, and patient satisfaction. After propensity score matching, baseline characteristics were comparable between the 2 groups (P > .05) . Compared with the control group, the mirabilite fomentation group had lower bleeding scores on postoperative day 3 and day 7 (group effect F = 5.73, P = .020; interaction F = 4. 11, P = .018) . The reduction in edema area and height was more pronounced (both P < .05) . Declines in the sensation of distension and visual analogue scale pain scores were more significant over time (distension: group effect F = 4.82, P = .031; pain: group effect F = 6.45, P = .014) . The incidence of urinary retention was lower in the mirabilite group (11 . 1% vs 30.6%, P = .044), with shorter time to first urination (8 .42 ± 1.25 hours vs 10.17 ± 1.47 hours, P < .001) . Wound healing time was reduced (14 .53 ± 2.17 days vs 17.06 ± 2.48 days, P < .001) . The total effective rate on day 7 was higher (94 .4% vs 77.8%, P = .04) . No severe adverse reactions were observed in either group, while patient satisfaction was higher in the mirabilite group (91 .7% vs 69.4%, P = .021) . Mirabilite fomentation as a nursing intervention can significantly alleviate postoperative edema, distension, and pain in patients with circumferential mixed hemorrhoids, reduce the incidence of urinary retention, accelerate wound healing, and achieve good safety and high patient satisfaction. It has clinical value for wider application. | | --- | | Abbreviation: ASA = American Society of Anesthesiologists, BMI = body mass index, EH ± II = external hemorrhoidectomy ± internal injection/ligation, PSM = propensity score matching, TCM = traditional Chinese medicine, VAS = visual analogue scale. | | Keywords: fomentation, mirabilite, mixed hemorrhoids, pain, postoperative edema, traditional Chinese medicine nursing, urinary retention | 1. Introduction Hemorrhoids are among the most common anorectal disorders, resulting from pathological dilatation and displacement of the rectal and anal venous plexus. Epidemiological studies have reported a prevalence of 40% to 60% among adults, with an upward trend due to changes in dietary habits, sedentary lifestyle, and abnormal defecation patterns. [1] Mixed hemorrhoids, formed by the fusion of internal and external hemorrhoids at the same location, particularly circumferential mixed hemorrhoids, are often accompanied by pronounced prolapse, bleeding, pain, and anal margin edema, which impose significant burdens on patients’ daily lives and psychological well-being. [2] Currently, surgical treatment remains the mainstay of management. External hemorrhoidectomy combined with internal ligation/injection (EH ± II) is widely adopted due to The authors have no funding and conflicts of interest to disclose. The datasets ge
