Comparison of the effects of dry heat versus moist heat therapy modalities on the intensity of pain and wound healing of episiotomies among postnatal women.
A Systematic review and meta-analysis of controlled trials.
Six databases searched for original articles using relevant keywords until September 10, 2023, without time or language restrictions.
REVIEW/ANALYSIS METHODS: All analyses employed Comprehensive Meta-Analysis (CMA) V.2. The measure of heterogeneity was computed using Cochran's Q-value. The I index was employed to quantitatively demonstrate heterogeneity. Statistical significance was reported for P-values <0.05 and I>50%.
Four quasi-experimental and three randomized controlled trials (RCTs) studies with moderate-to-good quality evidence met inclusion criteria. On the third to fifth day after the intervention in the dry heat group, the amount of pain was significantly lower than in the group that used moist heat [MD (95% CI) =-1.395 (-2.374, -0.416), P=0.005]. The use of a hair dryer significantly reduced pain (P=0.029), but an infrared lamp did not significantly reduce pain compared to moist heat (P=0.064). As compared to the moist heat group, the women using dry heat experienced better wound healing to the extent of 2.002 units of the REEDA (Redness, Edema, Ecchymosis, Discharge, Approximation) scale, which was statistically significant [MD (95% CI) = -2.002 (-2.785, -1.219), P<0.001].
Compared to sitz baths, dry heat reduced pain and improved episiotomy site healing in postnatal women. Therefore, dry heat, especially hair dryers, is suggested as a non-pharmacological strategy inside maternity hospitals, but additional targeted, high-quality trials are needed.
比较干热与湿热疗法对产后会阴切开产妇疼痛强度和伤口愈合的影响。
对对照试验进行系统评价和荟萃分析。

综述/分析方法：所有分析均采用 Comprehensive Meta-Analysis（CMA）V.2。使用 Cochran 的 Q 值计算异质性度量。使用 I 指数定量表示异质性。报告 P 值<0.05 和 I>50%时具有统计学意义。
四项准实验和三项随机对照试验（RCT）研究符合纳入标准，证据质量为中等至良好。在干预后的第三至第五天，干热组的疼痛程度明显低于湿热组[MD（95%CI）=-1.395（-2.374，-0.416），P=0.005]。使用吹风机可显著减轻疼痛（P=0.029），但与湿热组相比，红外线灯并未显著减轻疼痛（P=0.064）。与湿热组相比，使用干热的女性伤口愈合更好，REEDA（红肿、水肿、瘀斑、渗液、接近）量表的评分平均提高了 2.002 个单位，这具有统计学意义[MD（95%CI）=-2.002（-2.785，-1.219），P<0.001]。
与坐浴相比，干热可减轻产后妇女的疼痛并促进会阴切开部位的愈合。因此，干热，尤其是吹风机，被建议作为妇产医院的非药物策略，但需要更多有针对性的高质量试验。
