Abstract：Objective: To investigate the application value of the low tidal volume combined with low levels expiratory positive airway pressure to soft lenses kidney gravel. Methods: 80 cases were divided into two groups, with 40 cases in each group. In breath control, low tidal volume combined with low levels expiratory positive airway pressure was used in the observation group, while blot's breathing treatment was used in the control group, 30min after the intervention, the blood gas analysis, TNF-a, IL-6 and CRP levels as well as procedure-related indicators in the two groups were compared. Results: 30min after the intervention, pH level in the observation group was lower than that in the control group(P<0.05), PCO2 level in the observation group was lower than that in the control group(P<0.05). After the surgery, TNF-a, IL-6 and CRP level in the observation group were significantly lower than those in the control group(P<0.05), The operative time of the observation group was shorter than that of the control group(P<0.05), the number of cases of respiratory and failure proportion of soft lenses treatment in the observation group were lower than those in the control group(P<0.05). Conclusion: The low tidal volume combined with low levels expiratory positive airway pressure for soft lenses kidney gravel can maintain normal blood gas analysis, can significantly reduce the influence of surgery, anesthesia stress on patients, which is conductive to the surgical procedure.
