局麻内眼手术的血压和脉搏观察

The Observation of Blood Pressure and Pulse Rate on Intraocular Operation Under Local Anaesthesia

对100例局麻内眼手术前、后血压脉搏观察表明,术中血压脉搏均比术前高,尤以局麻后显著(P<0.001),术后2小时大部分恢复至术前,术后24小时均比术前下降.升高与精神因素、疼痛、球结膜下注射有关,而与不同年龄、普鲁卡因内加入少最新福林及是否患高血压或心脏病史无明显关系.提出术前血压控制在180/90mmHg 以下为安全,作好术前处理,麻醉应良好.

The observation of the blood pressures and pulse rates in 100 cases of intraocular operation before and after surgical manipulation under local anaesthesia indicated that every average values increased during operation, especially just after giving local anaesthesia.The systolic pressure increased 11 mmHg,the diastolic pressure 8 mmHg and the pulse rate 8/min. (P<0.001).Most of them recovened pre-operation 2 hours after surgery. The blood pressure and pulse rate 24 hours after surgery were less than those of pre-operation.During operation,the extent of blood pressure and pulse rate rising related with the emotional conditions,pain and subconjunctival injection,but seemed not much todeal with the ages of the patients,wea ther temperature,neophrynum adding to the injection procaine and also not much to relate with the hypertension or heart disease of the patients.It is suggestd that it is safer to control the blood pressure below 180/90mmHg before operation.Good preparation for the patient and perfect anaethesia for operation are needed.
