肾移植术前高压氧治疗对术后低氧血症发生的影响

Effect of preoperative hyperbaric oxygen therapy on the incidence of hypoxemia after renal transplantation

目的探讨术前实施高压氧治疗对肾移植患者术后低氧血症发生的影响。方法实验组55例肾移植受者术前实施高压氧治疗,对照组66例患者常规实施肾移植术。比较两组患者术后低氧血症发生率、肺部感染率、卧床吸氧时间、住院时间等方面的差异。结果实验组55例患者术后发生低氧血症12例,发生率为22%,对照组66例患者术后发生低氧血症20例,发生率为30%。实验组发生肺部感染4例,发生率为7%,对照组发生肺部感染14例,发生率为21%。实验组肾移植术后低氧血症及肺部感染的发生率低于对照组(均为P<0.05)。实验组和对照组患者术后卧床吸氧时间分别为(5.9±2.0)d、(6.8±2.6)d,住院时间分别为(17.7±3.7)d、(20.5±4.2)d。实验组患者卧床吸氧时间及住院时间均短于对照组(均为P<0.05)。结论术前实施高压氧治疗可以明显降低肾移植术后低氧血症及肺部感染的发生率,可以作为肾移植术后低氧血症的常规预防措施。

Objective To investigate the effect of preoperative hyperbaric oxygen therapy upon the incidence of hypoxemia in patients after renal transplantation. Methods In the experimental group, 55 patients received hyperbaric oxygen therapy prior to renal transplantation, and 66 counterparts in the control group underwent conventional renal transplantation. Postoperatively, the incidence of hypoxemia, pulmonary infection, time of in-bed oxygen inhalation and length of hospital stay were statistically compared between two groups. Results In the experimental group, 12 among 55 patients （22%） presented with hypoxemia after renal transplantation, and 20 of 66 （30%） in the control group. In the experimental group, 4 cases suffered from pulmonary infection with an incidence of b7%, and 14 （21%） in the control group. In the experimental group, the incidences of hypoxemia and pulmonary infection were lower than those in the control group （both P〈0.05）. Inthe experimental group, the time of in-bed oxygen inhalation and length of hospital stay were （5.9±2.0） d and （17.7±3.7） d, significantly shorter compared with （6.8±2.6） d and （20.5±4.2） d in the control group （both P〈0.05）. Conclusions Prior to renal transplantation, hyperbaric oxygen therapy can significantly reduce the risk of hypoxemia and pulmonary infection after renal transplantation, which can be served as a conventional preventive measure against the incidence of hypoxemia following renal transplantation.
