A Mixed-Methods Study of the Effect of Abdominal Binders on Opioid Use and Postoperative Pain After Cesarean Birth

ObjectiveTo compare levels of postoperative oxycodone use and incisional pain between two randomized groups—an intervention and a control.DesignMixed-methods design; quantitative data achieved via a randomized controlled trial, with qualitative data collected on binder use. The primary variable was oxycodone (in milligrams) required during the first 48 hours after birth, and the secondary variable was incisional pain levels measured on Postoperative Days 1 and 2.SettingAcute-care community hospital in Wheat Ridge, Colorado, and an acute care urban hospital in Denver, Colorado.ParticipantsA total of 220 individuals in the postpartum period after having cesarean birth.Interventions/MeasurementsParticipants were randomized to the intervention group (binder) or the control group (no binder). Data were collected on opioid usage for the first 48 hours. Participants in both groups were asked to rate their incisional pain on Postoperative Day 1 (24 hours after birth) and Postoperative Day 2 (48 hours after birth). Participants in the binder group were also asked to provide feedback on their experience wearing the binder.ResultsA total of 196 participants completed the study. The overall amount of oxycodone taken by individuals in the binder group was lower than that in the control group, but the difference was not statistically significant (p = .10). Pain scores in the binder group were significantly lower on Day 2 compared with the control group (p = .002). The majority of individuals in the binder group provided positive feedback about their experience wearing the binder.ConclusionIndividuals routinely receive medications to assist with pain management postoperatively. Because of growing concerns related to the nation’s opioid addiction crisis, there is interest in using multimodal treatments to achieve adequate pain control for individuals postoperatively. Abdominal binders are a low-cost intervention to assist with pain management and, given the results of this study, seem like a reasonable option to consider.     

液质联用技术联合网络药理学探讨白鲜皮治疗湿疹的作用机制＊

目的 采用液质联用技术分析白鲜皮中的主要化学成分；基于网络药理学技术研究白鲜皮治疗皮肤湿疹的活性成分、作用靶点及作用机制。方法 利用液质联用技术（LC-MS）对白鲜皮主要成分进行分析，通过质谱数据结合文献资料，对各主要成分进行快速识别；通过利用SwissADME数据库对白鲜皮潜在活性成分进行预测，筛选主要作用靶点。进行KEGG通路富集分析，最终得到白鲜皮成分-靶点-疾病-通路网络图。采用分子对接技术对主要成分和作用靶点进行验证。结果 从白鲜皮中共分析鉴定了12种成分，进一步筛选得到4种潜在活性成分，可作用于48个关键靶点和14条主要通路。结论 采用LC-MS技术结合网络药理学方法，可以快速分析白鲜皮的潜在活性成分，并初步揭示了成分-靶点-通路之间的关系。通过分子对接技术可以做作用靶点进行验证。     

“保胆”理念正误

胆囊切除术是公认的胆囊良性疾病的治愈手段，国内外学术界对于手术适应证和手术时机已有明确共识。近年来，“保胆手术”治疗胆囊良性疾病颇受热议，一些医生将“保护胆囊”的学术观点等同于“保留胆囊”的手术技术，这种误解可能导致病人出现差异性的预后。因此，临床医师应明晰“保护胆囊”理念与“保胆手术”的差别，对胆囊良性疾病的诊疗原则有正确的理解和应用。
