目的 :大量输血前后血钾浓度变化及高钾血症发生的影响因素分析。方法 :将近年我院收治的外伤手术并大量输血患者32例作为观察组,将同期外科手术未输血治疗患者32例作为对照组,观察对比两组输血前后血钾水平、高钾血症发生率及其影响因素。结果 :两组输血前血钾水平无显著差异(P>0.05),两组输血后血钾水平无显著差异(P>0.05)。观察组术后高钾血症发生率为18.8%,高于对照组的3.1%(P<0.05)。术前高血钾、术后p H值较低是术后高钾血症发生的主要影响因素(OR值分别为2.851、0.022,P均<0.05)。结论 :大量输血治疗不是非挤压伤、烧伤的外科手术患者高钾血症发生的直接原因,且输血前后血钾水平无异常变化,但仍需动态监测血钾水平,以减少相应并发症发生。
Objective: To analyze the changes of serum potassium concentration before and after heavy blood transfusion and the influencing factors of hyperkalemia. Methods: Thirty-two cases of traumatic operation and massive transfusion of blood transfusion in our hospital in recent years were selected as the observation group. Thirty-two patients who did not receive blood transfusion in the same period were selected as the control group. The levels of serum potassium and hyperkalemia before and after transfusion were observed and compared And its influencing factors. Results: There was no significant difference in blood potassium levels between the two groups before transfusion (P> 0.05). There was no significant difference between the two groups in blood potassium levels after transfusion (P> 0.05). The incidence of postoperative hyperkalemia in observation group was 18.8%, which was 3.1% higher than that in control group (P <0.05). Preoperative hyperkalemia, postoperative p H value is low postoperative hyperkalemia incidence of the main factors (OR values were 2.851,0.022, P all <0.05). CONCLUSION: Massive blood transfusion is not the direct cause of hyperkalemia in patients undergoing non-crush or burn surgery. There is no abnormal change of serum potassium levels before and after transfusion, but serum potassium levels need to be monitored dynamically to reduce the corresponding complications .
