Abstract:
Objective To analyze the efficacy of higher pressure recompression therapy (≥70 m) in the patients with decompression sickness (DCS),who displayed poor efficacy after initial recompression.Methods Forty patients with type Ⅱ DCS who received treatment in our hospital from September 2011 to June 2018 were selected as research subjects,and were designated as the study group (n =6) and the control group (n =34),in accordance with whether or not they had received recompression therapy before admission into hospital.The DCS patients of the study group were those transferred to our hospital after initial lower pressure recompression treatment with unsatisfactory results.These patients were treated with the Air Diving DCS Recompression Treatment Table (Table 5,Oxygen Breathing) developed by the Chinese Naval Medical Research Institute,at a pressure of 70 meters and with a total oxygen breathing time of 225 minutes.The patients of the control group were those with type Ⅱ DCS patients who received initial recompression treatment in our hospital within the same time span.Delayed time,application rate and treatment efficacy in the patients of the 2 groups were analyzed statistically.Results The delayed time (14.5 ± 4.9 h) of the secondary recompression group (or the study group) was obviously longer than that of the control group(4.3 ± 3.0 h) (P ＜ 0.001),and there was statistical significance when comparisons were made between them (P ＜ 0.001).The application rate of higher pressure treatment profile in the secondary recompression group (83.3％) was higher than that of the control group (5.9％),also with statistical significance (P ＜ 0.001).The treatment efficacy of the 2 group was identical,without statistical significance (P =0.585).Conclusion The higher pressure recompression profile could effectively treat those DCS patients who showed unsatisfactory treatment effects after initial recompression.For those DCS patients with delayed treatment,proper recompression profile could also achieve satisfactory treatment outcome.With the lack of low pressure oxygen-breathing treatment profile and other supplementary treatment methods,secondary higher pressure recompression treatment should be performed as early possible,in the treatment of the patients with type Ⅱ DCS.
