Objective To study the effect of sodium hyaluronate hydrogel in treating residual cavity on body surface after abscess drainage so as to provide new method to speed up the heal ing of residual cavity after body surface abscess drainageand reduce the frequency of dressing change and cl inic nursing workload. Methods From June 2007 to March 2008, 60 outpatients with body surface abscess drainage were randomly divided into hydrogel group (group A, 30 cases) and the control group (group B, 30 cases). In group A, there were 16 males and 14 females aged (49.5 ± 6.1) years, the disease course was (3.8 ± 0.6) days, and the volume of residual cavity was (4.19 ± 1.31) mL. In group B, there were 18 males and 12 females aged (50.2 ± 7.6) years, the disease course was (4.3 ± 0.5) days, and the volume of residual cavity was (4.04 ± 1.22) mL. There was no significant difference between two groups in gender, age, disease course and volume of residual cavity (P gt; 0.05). Residual cavity was smeared with 1 mL/cm2 sodium hyaluronate hydrogel in group A and drained by sal ine gauze in group B, the dressing was changed every two to three days. Residual cavity volume was recorded every four days, and the residual cavity volume, the frequency of out-patient dressing and the heal ing time residual of cavity were compared. Results The volume of residual cavity was (3.11 ± 1.12), (1.75 ± 0.95) and (0.55 ± 0.56) mL in group A, and was (3.39 ± 1.12), (2.64 ± 0.99) and (1.81 ± 0.81) mL in group B at 4, 8 and 12 days after treatment respectively, showing no significant differences at 4 days (P gt; 0. 05), but significant difference at 8 and 12 days (P lt; 0.01). Residual cavity heal ing time was (12.70 ± 2.78) days in group A and (20.27 ± 3.89) days in group B, and the frequency of dressing change was 5.53 ± 1.33 in group A and 9.13 ± 1.81 in group B, indicating significant differences between two groups (P lt; 0.01). Conclusion Sodium hyaluronate hydrogel can promote residual cavity heal ing, reduce the frequency of dressing change of out-patient and decrease the cl inic nursing care workload.
目的 探讨一期后位切开挂线左右侧切开引流手术治疗高位马蹄型肛周脓肿的临床效果。方法 前瞻性纳入2008年10月至2010年10月期间庆阳市人民医院收治的60例高位马蹄型肛周脓肿患者，将其随机分成2组，其中观察组30例，行一期后位切开挂线左右侧切开引流术；对照组30例，行一期切开挂线术。比较2组患者的临床疗效。结果 临床疗效观察组为优11例（36.67%），良17例（56.66%），差2例（6.67%），优良率为93.33%（28/30）；对照组为优5例（16.67%），良16例（53.33%），差9例（30.00%），优良率为70.00%（21/30）。观察组的临床疗效优于对照组（P＜0.05）。观察组患者术后肛缘水肿、肛门前移和肛门内陷的发生率以及创面愈合时间均低于或短于对照组（P＜0.05）。2组患者术后均获访1年，均无复发，肛门功能均正常，无畸形。结论 一期后位切开挂线左右侧切开引流术治疗高位马蹄型肛周脓肿的临床疗效确切，患者术后恢复良好，值得临床推广应用。
