[Grave complications of local anesthesia for cataract extraction: reports of 8 cases].

Cataract extraction performed under local anesthesia is not so safe. During a 2 years period, 8 patients have presented a complication: 3 patients are presented with diplopia, 4 patients are presented with eyeball perforation and 1 patient developed a central complication. All those complications are caused by the superior peribulbar injections of anesthetics. A survey of the different etiologies of the superior rectus muscle blow and of eyeball perforation is given.

[Total intravenous anesthesia for two patients complicated with myotonic dystrophy].

Total intravenous anesthesia with propofol, fentanyl and ketamine (PFK) was given to two patients complicated with myotonic dystrophy. Case-1: A 42-year-old female underwent a hemithyroidectomy. Anesthesia was induced slowly with intravenous ketamine 20 mg and propofol 60 mg. Her tracheal intubation was performed smoothly without any muscle relaxants. Anesthesia was maintained with propofol infusion of 5 mg.kg-1.h-1, ketamine infusion of 0.3 mg.kg-1.h-1 and fentanyl 200 micrograms in total. She regained consciousness 20 minutes after the end of propofol infusion, and 15 minutes later, her trachea was extubated without any troubles. Case-2: A 41-year-old female underwent a removal of left parotid tumor. Anesthesia was induced slowly with ketamine 40 mg and propofol 100 mg intravenously. Anesthesia was maintained with propofol infusion of 5-10 mg.kg-1.h-1, ketamine infusion of 0.5 mg.kg-1.h-1 and fentanyl 350 micrograms in total. No muscle relaxant was used through the surgical procedure. Emergence from anesthesia was observed 10 minutes after the end of propofol infusion and her trachea was extubated. When a nasogastric tube was pulled out, her respiration stopped suddenly and she was intubated again only for two hours without any troubles. In both cases their serum CPK levels and rectal temperatures were very stable. PFK method would be a choice for patients with myotonic dystrophy.

[Accidents and complications seen during anesthesia and postoperative recovery in coronary surgery].

One hundred and six cases of myocardial revascularisation ECC performed during 1976 and 1977 were reviewed in order to assess the accidents and complications seen in surgery of this type. The course of the operation, and above all during the pre-ECC phase, was felt to be marked above all by hypertensive crises. During the immediate postoperative phase the picture was dominated by haemodynamic problems. Moderate left ventricular failure was common and responded rapidly to restoration of water and electrolyte and blood volume balance. Sympathomimetic amines were also used as necessary. Severe low output states were seen in only 8.5 per cent of cases. Analysis of factors interfering with the operation showed that the prior myocardial state had the most influence on the postoperative course.

Diplopia as a complication of local anesthesia: a case report.

Diplopia caused by local anesthesia at the superior posterior alveolar nerve for the removal of the maxillary third molar is a rare complication. The diplopia is due to facial palsy of the oculomotor muscles of the globe. This paper describes the case of a 22-year-old woman, in whom diplopia was observed after an overall uncomplicated removal of the semi-impacted third molar. Possible causes of the anesthetic effects are reported. The most accepted explanation is that the anesthetic diffuses on the abducent nerve in the cavernous sinus. The necessary actions that the dental surgeon must perform are reported.

The continuous-injection technique to reduce complications during retrobulbar anesthesia.

Retrobulbar as well as peribulbar anesthesia remain relatively risky procedures; retrobulbar hemorrhage and especially globe penetration or perforation can have blinding consequences. Our continuous-injection-technique greatly reduces these risks whether used for retrobulbar or peribulbar anesthesia. If the ophthalmologist starts injecting the agent while advancing the needle, the fluid pushes tissues away, possibly preventing a hemorrhage. Since resistance against the plunger is instantaneously experienced if the needle impacts the sclera, the ophthalmologist is adequately warned before actual perforation of the sclera occurs.

[Multifactorial index of the risk of complications related to anesthesia].

Anaesthetic risk has been studied until now only in terms of mortality rates, and by single factor analysis. A multifactorial index of anaesthetic risk, taking into account all major complications related to anaesthesia that occur during--or within 24 hours of--surgery is proposed. Data were collected in a prospective survey among a representative sample of anaesthesias. The logistic model included a sample of 232 complications and a control group of 1 642 anaesthesias with no complications. Eight factors related to the patient's condition, and to the kind of surgery performed, were considered. Only six were found to have prognostic value, and--among them--the "previous complications" factor stood out. There was a good concordance between predicted and observed risk. The index may be used for a preoperative estimate of anaesthetic risk.
