观察肩关节镜下肩袖修补手术对血浆钾、钠、氯的影响。

收集22例肩关节镜下行肩袖修补术患者，观察术前术后血清钾、钠、氯含量的变化。

肩关节术后测定血中钾、钠、氯浓度，发现与术前相比均有不同程度的变化，均在正常范围。但手术前后钾和氯变化差异具有统计学意义（P<0.05），其中钾降低，氯升高。

应用肩关节修补肩袖撕裂，术后钠、钾、氯均有不同程度变化，其中有部分患者出现低钾血症或高氯血症，应引起重视。

Arthroscopic surgery is a minimally invasive surgery developed in China in recent years. In addition to the knee joint, arthroscopy can also be used for the diagnosis and treatment of most people's shoulder diseases with small tissue trauma, fine operation, intuitive advantages. During arthroscopy, continuous lavage is required to expand the joint and provide a clear surgical field. Currently, isotonic solution (such as normal saline or lactate ringer's solution) has been used as a routine arthroscopic lavage solution, and its safety has been confirmed. However, shoulder arthroscopy requires high pressure and a large amount of washing fluid, and there has been no relevant report on whether it affects electrolytes in the body.

To observe the effect of rotator cuff repair on plasma potassium, sodium and chloride under shoulder arthroscopy.

Serum potassium, sodium and chlorine were collected from 22 patients who underwent rotator cuff repair under arthroscopy, and the changes were observed and recorded.

Potassium, sodium and chloride concentrations in blood were measured after shoulder joint surgery, and it was found that compared with those before surgery, there were different degrees of changes, but all in the normal range. However, there was a significant difference between potassium and chlorine before and after surgery with P<0.05, in which potassium decreased and chlorine increased.

With the application of shoulder arthroscopic repair for rotator cuff tear, postoperative sodium, potassium and chlorine all have different degrees of change, among which some patients have hypokalemia or hyperchloremia, and should be taken seriously.
