Cardiac arrest after isoflurane anaesthesia in a patient with Duchenne''s muscular dystrophy 总被引:4,自引:0,他引:4
An 8-year-old boy known to have Duchenne's muscular dystrophy suffered a cardiac arrest 10 minutes after he regained consciousness after isoflurane anaesthesia for an orchidopexy procedure. Resuscitation was successful 2 hours after the start of external cardiac compression and after correction of hyperkalaemia and the administration of dantrolene. He later developed myoglobinuria elevated creatine kinase and a metabolic and respiratory acidosis. He demonstrated a delayed increase in rectal temperature. 相似文献

Patients with Duchenne muscular dystrophy (DMD) are at highrisk of perioperative complications. DMD may be accompaniedby heart failure resulting from dystrophic involvement of themyocardium, which can be subclinical in the early stages ofthe disease. This case demonstrates that a normal preoperativeECG and echocardiograph cannot exclude the development of heartfailure during anaesthesia in DMD patients undergoing majorsurgery.

Trans‐esophageal echocardiography (TEE) and/or central venous pressure (CVP) monitoring are important in the anesthetic management of spine fusion of pediatric patients with severe muscular weakness. This case highlights an unusual situation of apparent acute right ventricular mechanical obstruction after prone positioning and its prompt recognition with CVP monitoring. The anesthetic management of a patient with congenital muscular dystrophy, an uncommon neuromuscular disorder, is presented. Good communication and planning between the anesthesiology and surgical teams allowed completion of the procedure using a lateral approach. 相似文献

Anesthesia may be administered to patients with Duchenne's muscular dystrophy, but cases are reported in which apparently healthy children suffer hyperkalemic cardiac arrest. We present the case of a 5-year-old boy whose muscular dystrophy was discovered following a fatal, perioperative cardiac arrest in the postanesthesia care unit. 相似文献

Hemodynamic effect of the prone position during anesthesia 总被引:1,自引:0,他引:1
We studied 21 patients undergoing lumbar spinal surgery under halothane anesthesia on a convex saddle frame, in order to determine the hemodynamic effect of the prone position. A thermodilution pulmonary arterial catheter was placed in 14 patients (Group PA-1: n = 8; and Group PA-2: n = 6), and an inferior vena caval catheter in the remaining seven patients (Group IVC). Group PA-1 and Group IVC patients were placed in the prone position on a convex saddle frame. In the prone position, the cardiac index (CI) decreased significantly from 3.1 +/- 0.5 to 2.5 +/- 0.3 (l.min-1.m-2, mean +/- s.d., P less than 0.01) without accompanying significant changes in the other hemodynamic variables in Group PA-1. The postural change in Group IVC did not exert a significant effect on the inferior vena caval pressure. Group PA-2 were initially placed in the flat prone position on a flat saddle frame, which produced no significant changes in the hemodynamic variables. Then the convex curvature of the frame was adjusted to the grade appropriate for surgery, which produced a significant reduction in CI (from 2.9 +/- 0.3 to 2.4 +/- 0.4, P less than 0.05). We conclude that the prone position itself may not interfere with the circulatory function. The prone position using a convex saddle frame causes significant reductions in CI, but little change in the other hemodynamic variables. 相似文献

BACKGROUND: In patients with Duchenne's muscular dystrophy (DMD) recovery from neuromuscular block is delayed. It has been assumed that this is because of a higher potency of muscle relaxants in this patient cohort. We determined the peak effect, and the time course of action of rocuronium 0.3 mg x kg(-1) (ED(95)) in DMD patients. METHODS: Twenty-four patients (12 with DMD and 12 controls; aged 10-18 years) were studied. All patients were anesthetized with propofol and fentanyl/remifentanil. Neuromuscular transmission was monitored by acceleromyography. After induction all patients received a single dose of rocuronium 0.3 mg x kg(-1). The complete time course of action as onset, peak effect and spontaneous recovery was recorded. RESULTS: The onset time (s) to maximum block was significantly (P < 0.01) prolonged in DMD patients (median: 315; range: 120-465) compared with controls (195, 75-270). The peak effect (% twitch depression relative to baseline) was not different between the groups (DMD: 59-100; controls: 28-100). In the DMD group, recovery was significantly (P < 0.01) delayed compared with controls at all recorded time points. The clinical duration (min) was 40.3 (22-89) in the DMD group vs 9.8 (6-17) in the control group (P < 0.01). CONCLUSIONS: The similar peak effect in both groups does not confirm the thesis of rocuronium having a higher potency in DMD patients. The documented very long recovery after the ED(95) of rocuronium emphasizes the need for careful assessment of neuromuscular function in DMD patients. 相似文献

A randomised single-blind trial was performed to compare the effects on cardiac rhythm of isoflurane and halothane in 100 dental outpatients having extractions under general anaesthesia in the dental chair without tracheal intubation. The incidence of supraventricular dysrhythmias did not differ significantly. No patient in the isoflurane group developed a ventricular dysrhythmia, whilst nine of those who received halothane did so (p = 0.0013). The quality of anaesthesia was acceptable in the isoflurane group, but induction time was longer (p less than 0.05) and the maximum heart rate was faster (p less than 0.01). There was no difference in the maximum end tidal carbon dioxide concentrations measured in a further 20 cases. 相似文献

Accidents, near accidents and complications during anaesthesia A retrospective analysis of a 10-year period in a teaching hospital 总被引:7,自引:0,他引:7
A retrospective analysis is presented of all reports of faults, accidents, near accidents and complications associated with anaesthesia in one hospital from 1978 to 1987. 113,074 anaesthetics were administered in that period, of which 97,496 were for noncardiac procedures. There were 148 reports; 39 were of dental damage. Peri-operative cardiac arrests during noncardiac surgery were reported 29 times. Sixteen of these were fatal. Anaesthesia was thought to have played an important role in 13 cardiac arrests (1 per 7500 anaesthetics) and six were not successfully resuscitated (1 per 16,250 anaesthetics). There were 12 reports of postoperative peripheral neuropathies (1 per 9422 anaesthetics). Failure to check, lack of vigilance and inattention or carelessness were the most frequently associated factors with the rest of the reports. 相似文献

A 54-year-old patient with Becker muscular dystrophy and dilated cardiomyopathy underwent laparoscopic cholecystectomy under total intravenous anesthesia. Muscle relaxation was induced by rocuronium (0.4 mg/kg body weight) under train-of-four (TOF) ratio monitoring. The TOF ratio was 0 at intubation, and 0.2 at the end of surgery. Residual muscle relaxant activity was successfully reversed by sugammadex (2 mg/kg body weight) without any hemodynamic adverse effects (TOF ratio 1.0 at extubation). The clinical and hemodynamic findings suggest that sugammadex can be safely used in patients with Becker muscular dystrophy and dilated cardiomyopathy. 相似文献

目的探讨俯卧分腿位一期经皮肾镜(PCNL)联合逆行输尿管软镜(RIRS)治疗复杂性铸型结石的可行性、有效性和安全性。
方法回顾性分析我院2015年8月至2019年8月93例复杂性铸型结石患者的临床资料,其中PCNL组50例仅行PCNL,PCNL+RIRS组43例一期行PCNL联合RIRS,术前肾结石情况采用S.T.O.N.E评分系统进行评估;两组均在截石位下置入输尿管支架管(剪去头端),PCNL组改为俯卧位,PCNL+RIRS组改为俯卧分腿位,比较两组的手术时间、术后血红蛋白下降值、术后发热率、再次手术率、结石清除率、术后住院天数及并发症。
结果两组的术前基本资料差异无统计学意义,所有患者均顺利完成手术,PCNL+RIRS组需要建立的通道显著少于PCNL组;PCNL+RIRS组在血红蛋白下降值、结石清除率、再次手术率、平均住院天数上均明显优于PCNL组;虽然两组在手术时间、术后发热率、手术并发症差异无统计学意义,但是PCNL组有1例需要介入栓塞患者,并且PCNL组患者术后发热比例高于PCNL+RIRS组,差异无统计学意义可能与本研究例数较少有关。
结论俯卧分腿位一期经皮肾镜联合逆行输尿管软镜治疗复杂性肾结石安全有效,可以减少穿刺通道和术中出血,提高结石清除率,降低再次手术率。 相似文献

A 56-year-old woman with diabetes mellitus was scheduled for bilateral kidney lithotomy. She was in the prone position for about seven hours during operation. At the end of operation, arterial blood gas analysis showed PaO2 64 mmHg and PaCO2 44 mmHg under 100% oxygen inhalation through a face mask, and the chest x-rays showed elevation of the right diaphragm. Her trachea was intubated again. The right diaphragm returned to the preoperative level by positive pressure ventilation on supine position. Hypoxemia disappeared when the patient was placed in the sitting position, and the trachea was extubated. The right diaphragm returned to the normal level on the 1st postoperative day, but hypoxia continued until the 6th postoperative day with the patient on supine position. We speculate that the diaphragmatic paralysis was caused by over-extension of the neck for a prolonged period, and that the patient might have been susceptible to nerve injury due to underlying diabetes mellitus. 相似文献

A comparison of the antibacterial activity of levobupivacaine vs. bupivacaine: an in vitro study with bacteria implicated in epidural infection 总被引:3,自引:0,他引:3
The purpose of the study was to compare the antibacterial activity of bupivacaine with levobupivacaine against a range of bacteria implicated in epidural infection to determine whether any differences existed between the two drugs. Concentrations of 0.125%, 0.25% and 0.5% bupivacaine and levobupivacaine were inoculated with suspensions of either Staphylococcus epidermidis, Staphylococcus aureus or Enterococcus faecalis. After incubation, the mixtures were plated onto blood agar and colony counts were recorded after a further period of incubation. The minimum bactericidal concentration of local anaesthetic against the three bacteria studied was found to be 0.25% for bupivacaine and 0.5% for levobupivacaine showing racemic bupivacaine to have a more potent antibacterial action than levobupivacaine. This finding suggests that the dextrobupivacaine isomer of racemic bupivacaine has a more potent antibacterial action than the levobupivacaine isomer. 相似文献
