[Clinical study on action of artificial respiration produced by pressing in massage under anesthesia for lumbar
1Guanganmen Hospital, China Academy of Traditional Chinese Medicine, Beijing.
Objective:
To observe whether the gas exchange is sufficient for the requirement of body when the patient was prone in position and pressed in the course of massage under intravenous anesthesia with sodium pentothal (SP) for the treatment of lumbar intervertebral disc prolapse.
Methods:
The oxygen would not be given to the patients whose heart and lung functions were good during the course of anesthesia and massage, respiratory function and blood gas analysis were studied on 20 patients selected randomly.
Results:
Tidal volume was smaller and respiratory rate was faster than normal respiration. Saturation pulse oxygen was still normal in all patients. There were no significant changes in blood gas analysis before spinal injection and after massage (P > 0.05).
Conclusion:
The pressing could attain the action of artificial respiration. The respiration pattern was similar to high frequency positive pressure ventilation. The action of vibration and diffusion had normal respiratory effect.
