Background
Because of the influence of hypoxia, the degree of shock of patients with traumatic hemorrhagic shock (HTS) in high altitude area will be aggravated in a short period of time. There is a difference in treatment strategy compared with the low altitude area. At present, the relevant literature reports are growing. However, there is no systematic review of these clinical evidences. Therefore, this study aims to synthesize existing literature on the treatment strategy of HTS patients in high altitude area.
Methods
By searching PubMed, Medline, Embase, CNKI, CBMdisc, VIP and the Cochrane Database of Systematic Reviews, searched from inception until March 1, 2020. The clinical trial of HTS patients at high altitude, which was conducted by qualitative analysis to extract data, classify, summarize and arrange information.
Results
Overall, 254 articles were identified, of which 13 relevant articles were identified following screening. Clinical practice and rationale for treatment decisions mainly involve the following 6 aspects: (1) effective prehospital treatment (hemostasis, bandaging, ventilation and establishment of venous access, etc.); (2) long time and low concentration oxygen supply; (3) limited rehydration, the amount of rehydration being 1–2 times of the patient's blood loss; (4) the microcirculation of patients was improved by drug intervention and rewarming; (5) lanatoside C or cedilanid was used to improve the cardiopulmonary function of patients; (6) 5% sodium bicarbonate was used to improve the acid-base balance of patients. In addition, ARDS, MOF and PTPI are the main complications leading to death.
Conclusions
The level of oxygen supply, rehydration and other treatment strategies for HTS patients in high altitude area are different from those in low altitude areas. The dynamic changes of physiological indexes in the process of treatment are important signs of adjusting the treatment plan. Effective prehospital first aid and rapid medical transport have a positive effect on patients' later rehabilitation.
