Two hundred and ninety-nine patients undergoing physical check-up were randomized to receive intramuscular meperidine 50 mg and Hyoscine-N-Butylbromide (buscopan) 20 mg (Group IM-MB, n = 57) or intravenous midazolam 0.05 mg/kg, meperidine 1 mg/kg and buscopan 20 mg (Group IV-MMB, n = 242) before colonoscopy. All patients were closely observed and arterial oxygen saturations (SaO2) were monitored with pulse oximeter in Group IV-MMB. The demographic data of both groups were similar. There were significantly more severe pain responses (grimacing, moaning, shouting for pain, abdominal rigidity and body moving during colonoscopy) in Group IM-MB (51%) than in Group IV-MMB (13%) (p < 0.01). In immediate procedure recall after recovery from medications, 39% of Group IM-MB remembered severe pain during colonoscopy and only 3% of Group IV-MMB did (p < 0.01). 92% of Group IV-MMB who felt satisfactory with the medications were significantly higher than 21% in Group IM-MB (p < 0.01).

{"title":"[Anesthetic management of intraoperatively diagnosed pheochromocytoma--a case report].","authors":"P S Tsai, K L Wong","doi":"","DOIUrl":"","url":null,"abstract":"Pheochromocytoma is a catecholamine secreting tumor originating from the adrenal medulla (up to 90%), or from the chromaffin tissue along the paravertebral sympathetic chain. The hallmark of pheochromocytoma is paroxysmal hypertension associated with diaphoresis, headache, tremulousness, and palpitations. The triad of diaphoresis, tachycardia, and headache in hypertensive patients is highly suggestive of pheochromocytoma. Other symptoms like flushing, nausea, vomiting, personality changes, and visual disturbances may however cast doubt on the diagnosis of pheochromocytoma. Death resulting from pheochromocytoma is usually due to congestive heart failure, myocardial infarction, or intracerebral hemorrhage. Although less than 0.1 percent of patients with hypertension have a pheochromocytoma, nearly 50 percent of the mortality with unsuspected pheochromocytoma occurred during anesthesia and surgery or parturition. Patients of unsuspected pheochromocytoma have higher risk for surgery, because some mandatory pre-op medical treatments might have been ignored. It is also a challenge to anesthesiologists to handle unsuspected hypertensive crisis during anesthesia and surgery. We presented such a case of unexpected Pheochromocytoma which was mis-diagnosed by the surgeon and was treated as an ordinary adrenal gland tumor and was scheduled for surgical operation. When the patient was undergoing excision of the tumor, manipulations of the tumor initiated an tremendous elevation of the blood pressure. Upon reviewing her history of normotension with visual disturbance, nausea and restlessness, she was immediate treated as with a pheochromocytoma. Appropriate managements were applied to control her abnormally high fluctuating blood pressure with success and with no complications or adverse effect.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":77247,"journal":{"name":"Ma zui xue za zhi = Anaesthesiologica Sinica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19289209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All the cases are impressed of pheochromocytoma that predominantly excrete norepinephrine. Anesthesia was induced with fentanyl, 2.5% sodium thiopental, valium and atracurium. Labetalol was used as antihypertensive agent and was given in repeated bolus (up to total dose of 2 mg/kg) intravenously before skin incision and no supplemental dosage was given later on. The anesthesia was maintained with nitrous oxide, oxygen, isoflurane and atracurium. Blood pressure, heart rate and arterial blood gas analysis were recorded. After giving intravenous labetalol, mean systolic blood pressure and heart rate declined by 26.2% and 29.76% respectively when compared to preanesthetic values. Although bradycardia was noted after administration of labetalol, it seemed acceptable except for one patient who needed atropine right after receiving labetalol and another patient who needed levophed infusion after tumor removal. During tumor removal, the blood pressure of all patients was stable except one patient who needed sodium nitroprusside infusion together with labetalol to help control the elevated blood pressure. All the patients in our study had no sequela postoperatively. We concluded that total dose of labetalol (2 mg/kg) administered intravenously at the beginning of anesthesia was possible to control blood pressure during the resection of pheochromocytoma under general anesthesia even in the case of poor preoperative blood pressure control.","PeriodicalId":77247,"journal":{"name":"Ma zui xue za zhi = Anaesthesiologica Sinica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19290194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
