ABSTRACT
Objective To explore the effect of a new prone position for general anesthesia.Methods 50 patients in the group were made a retrospective study:All the 50 patients needed prone position surgeries under general anesthesia.After awake flexible fiberoptic intubation,with the anesthesia of thyrocricoid puncturing the intra-trachea surface,has been taken,patients lied in the prone position according to their own comfort with the guide of medical staff,which was followed by anesthesia induction and the operation.The SBP,DBP,HR and RPP were recor-ded at different point of time after patients entered the operation room.Results 33 cases of 50 patients completed the whole process successfully and the indexes at the time of the intubation had no significant difference with those at basic state(all P >0.05).17 operations suffered discomfort.The SBP,DBP,HR and RPP in these patients were (159.2 ±25.9)mmHg,(97.2 ±11.6)mmHg,(98.2 ±9)beats per minute and (16 028 ±6 725)respectively, which were higher than those at basic state(t =2.698,2.802,5.720,8.905,all P 0.05).Conclusion It is technically simple and easy to operate,the way that patients waiting for prone position surgeries lie in the prone position by themselves with awake flexible fiberoptic intubation lightens the workload of medical staff and reduces complications of the intubation,which is optional in clinical situations.
ABSTRACT
Objective To explore the feasibility of the ultrasonic atomization surface anesthesia with lido-caine for awake fiberoptic endotracheal intubation in patientsˊautonomous position -display before general anesthesia and to evaluate its advantages.Methods 68 adult patients who needed prone position for elective surgery under general anesthesia were selected and randomly divided into two groups,the control group and the treatment group,each group in 34 cases.In control group patients were received surface anesthesia of cricothyroid membrane puncture.In treatment group,nebulized 2% lidocaine with ultrasonic nebulizer was used for topical anesthesia.Patients lied in the prone position according to their own comfort with the guide of the medical staff in the waking state after an awake fiberoptic endotracheal intubation.The statistics of mean arterial pressure (MAP)and heart rate (HR)were recorded respectively in the basal state(T0),in the time instantly after intubations(T1 ),in the 3 minute after intubations(T2 ) and in the time instantly after the body turning(T3 ).Choking cough response were recorded during endotracheal intubation.Patients were asked the efficacy of surface anesthesia and the tolerance for awake intubation after operation.Results Patients in both two groups completed the whole process smoothly.MAP and HR had no signifi-cant differences between the two groups in the same time point (all P >0.05).There were no statistical significance between the two groups in choking cough response,the time of surface anesthesia and intubation,neither (all P >0.05).Conclusion The surface anesthesia with lidocaine by continuous ultrasonic atomizing inhalation is a good and simple method deserving generalization with plenty merits and is practicable for patients to display position autonomously. This method have the advantages of small operation,it will and can replace cricothyroid membrane puncture.
