大面积烧伤病人早期动脉血气检查相关指标临床分析
[Abstract]:Objective by summarizing and analyzing the changes of arterial blood gas and acid-base balance of large area burns in our hospital in recent years, the value and the specific value range of the environmental monitoring indexes of pH, SB, PaCO2, alkali residue, lactic acid and PaO2 in the treatment of burn were discussed, and the effects on the change and prognosis of the burn patients were also discussed. Materials and methods according to certain inclusion and exclusion criteria, 59 cases of large area burn patients admitted from December 2010 to 09 months of 2014 were collected from the Department of burn of Guangxi Medical University. The data were divided into the death group and the survival group. The arterial blood pH value, SB, PaCO2, alkali residue, lactic acid and PaO2 were statistically analyzed in two groups of patients. The data were examined by t. Results or x2 test. Results 1, patients with large area burns were (7.24 + 0.08) and (7.31 + 0.09) in the survival group (7.28 + 0.11) in the survival group and (7.35 + 0.08) in the 24h segment after injury, and (7.36 + 0.13) in the 48h segment after injury (7.36 + 0.13) and (7.41 + 0.04) in the survival group (7.41 + 0.04). There were significant differences in pH value in each period of each group (P0.05). The mortality of normal patients in 48h segment after injury was 10%, the mortality of patients with pH value greater than 7.45 was 40%, the mortality difference in two groups was statistically significant.2, the SB of arterial blood in 8h segment after injury was (16.5 + 2.8) mmol/L, and the survival group was (18.6 + 3.8) mmol/L; the SB mean of 24h segment after injury was (17.4 + 4.1) mmol/L, and the survival group was (20.4 + 3.6) mmol. The SB values in the two groups were significantly different (P0.05). The SB in the 48h segment after injury was (21.7 + 6.1) mmol/L, and the survival group was (23.3 + 2.7) mmol/L. two (P0.05). The mortality rate of 48h segment SB greater than 27mmol/L was 50%, the mortality rate of the normal SB patients was 11.8%, and the mortality difference in the two group was significant. There was no significant difference in the mortality between the PaCO2 and the normal patients. The mortality of paco235mmhg, paco245mmhg and PaCO2 was statistically significant.4. The arterial blood be in the 8h segment after injury was (-10.5 + 4.4) mmol/l and the survival group was (-7.5 + 4.3) mmol/l. The survival group recovered to (-4.9 + 3.8) mmol/l, and the mean be in the 48h segment after injury was recovered to (-3.5 5.7) mmol/l, the survival group recovered to (-1.0 + 2.8) mmol/l. two, and the be values in each time period were significantly different (P0.05).5. The arterial blood lactic acid was (5.3 + 2.3), and the survival group was 4.3 + 1.9, and the lactic acid in the dead group after injury was (4.5 +). 2.9) mmol/l, the survival group was (3.3 + 1.8) mmol/l, and the lactate in the 48h segment after injury was (3.5 + 1.4) mmol/l, the survival group was (2.5 + 1.3) mmol/l. two after the injury (P0.05).6. The mortality difference between the patients with pao280mmhg in 24 hours and 48 small periods after injury and in the normal PaO2 patients was statistically significant. The remaining PaO2 was normal. There was no significant difference in mortality between patients with pao280mmhg and patients with pao2100mmhg. Conclusion 1, 8 hours after injury, the pH value of less than 7.3 indicates a serious condition and a higher mortality rate. The treatment in 24 hours after injury has a significant impact on the prognosis. To 48 hours, the patients with pH value are increased and have a higher mortality rate. In clinical, we should pay attention to.2. The sb value of 8 hours after large area burns is above 18.5mmol/l, and the death rate of those who have reached 20mmol/l above 20mmol/l 24 hours after injury is low; the mortality of patients with sb greater than 27mmol/l after 48 hours after injury is also high. It is important to pay attention to.3 in clinic, and large area burns have an important influence on the prognosis, and we should actively deal with.24 hours in clinical. It is necessary to improve the.4 of respiratory alkalosis in time and effectively. The arterial blood be content and the mortality rate of the patients with large area burns are more than -7.5mmol/l 8 hours after injury. The prognosis is better than -5mmol/l after 24 hours after injury. The content of lactic acid in the arterial blood and the death rate of the large area burn patients are in accordance with the death rate. 24 hours after the injury, the lactic acid is controlled in 3.5mmol/l. The following can effectively reduce the mortality rate.
