Abstract:
Objective:To analyze the value of the waveform curve and quantitative value of end-respiratory carbon dioxide partial pressure (P ETCO 2) in resuscitation monitoring of patients with general anesthesia. Methods:One hundred and forty-two patients who performed operation under general anesthesia and entered into the anesthesia recovery room in Zhejiang Xin′an International Hospital from April 2019 to September 2019 were selected. According to the method of random number table, all the 142 cases were divided into control group and observation group, with 71 cases in each group. Routine monitoring during general anaesthesia resuscitation such as blood pressure (BP), respiratory frequency (RR), blood oxygen saturation (SpO 2), arterial partial pressure of carbon dioxide (PaCO 2) was performed in the control group. On this basis, changes in P ETCO 2 waveform curve and quantitative value was continuously monitored in the observation group.The abnormal events rate, checkout time, anesthesia resuscitation time and residence time in the anesthesia recovery room of two groups during anesthesia resuscitation were recorded. Besides, the relationship between P ETCO 2 and PaCO 2 was analyzed. Results:The levels of RR, BP, SpO 2, PaO 2 in both groups were in the normal range during general anesthesia resuscitation, and P ETCO 2 in the observation group was also in the normal range. During general anesthesia resuscitation, the abnormal events rate in the observation group was was higher than that in the control group: 12.68%(9/71) vs. 7.04%(5/71); besides, the checkout time of abnormal events, anesthesia resuscitation time and residence time in the anesthesia recovery room in the observation group were shorter than those in the control group: (1.61 ± 0.52) min vs. (2.11 ± 0.69) min, (35.98 ± 10.66) min vs. (46.75 ± 15.03) min and (62.52 ± 19.63) min vs. (76.97 ± 15.41) min, there were significant differences ( P<0.05). P ETCO 2 was negatively correlated with SpO 2 ( r=-0.335, P=0.004), while P ETCO 2 was positively correlated with PaCO 2 ( r=0.751, P<0.001). Conclusions:Monitoring P ETCO 2 of patients during general anesthesia resuscitation can improve the detection rate and timeliness of abnormal events, promote the recovery of anesthesia and help to reduce the occurrence of adverse events.
