[Brachial plexus block and locoregional anesthesia of the upper limb. Apropos of 50 cases].

The authors report their experience about 50 cases of supra clavicular plexus block realised by Kulenkampff method. The anesthesia obtained has been complete in 84% of cases and in the 16% remaining general anesthesia was necessary to permit surgery. A case of late moderate pleural detachment and a case of post anesthesia paresthesia both spontaneously resolving were registered. Actually the adoption of perivascular techniques of brachial plexus anesthesia (interscalenic, supraclavicular, axillary) have greatly improved the performance of this variety of upper limb locoregional anesthesia, thus reducing the percentage of failure and eliminating or reducing the risk of pneumothorax. Locoregional anesthesia of the upper limb should constitute a daily method in the surgery of upper limb and not a technic subordinated to the contra-indications of general anesthesia.

[Maternal prognostic factors in severe eclampsia].

Sixty cases of severe eclampsia were treated in an intensive care unit between January 1989 and September 1993. Mean age was 26, and 70% of patients were primipara. The pregnancy has been unsupervised in almost all cases. All had visceral lesions and/or hematologic problems and there was impaired conscious level in 9 cases out of 10. Medical treatment involved the control of seizures and of hypertension. Cesarean section was performed in 34 cases. The maternal death rate was 23.3%. Our experience indicates that mortality depends upon visceral lesions (cerebral, disseminated intravascular coagulation, acute pulmonary edema, Hellp syndrome). Better awareness of severity factors in preeclampsia improves both maternal and fetal prognosis by precisely indicating the best time for fetal extraction.

Lidocaine-clonidine retrobulbar block for cataract surgery in the elderly.

BACKGROUND AND OBJECTIVES: Clonidine, an alpha-2-adrenoreceptor agonist, has been shown to decrease intraocular pressure (IOP) and to have some analgesic and sedative effects when it is used in premedication for ophthalmic surgery. This study was designed to investigate the efficacy of lidocaine-clonidine retrobulbar block for cataract surgery with respect to its effect on IOP, analgesic action, and sedative effects. METHODS: Sixty elderly patients (ASA status I and II) were allocated randomly to receive in a prospective double-blind manner retrobulbar block for cataract surgery. Group I (n = 30) received 3-4 mL of 2% lidocaine with 1 mL saline, while group 2 (n = 30), received 3-4 mL of 2% lidocaine with clonidine 2 micrograms/kg. RESULTS: A large decrease in intraocular pressure from 13.5 +/- 4.6 to 7.7 +/- 3.7 mm Hg (P < .01) and a small but significant reduction of both systolic and diastolic blood pressure were observed 20 minutes alter the retrobulbar block in patients receiving clonidine, while no changes occurred in the control group. The median duration of analgesia and akinesia was greater in the lidocaine-clonidine group (241 +/- 88 minutes and 80 +/- 20 minutes, respectively) as compared with the lidocaine group (128 +/- 24 minutes and 70 +/- 20 minutes, respectively) (P < .01, P < .05). Sedation scores were greater in group 2 from the 10-minute point (P < .01). CONCLUSIONS: Addition of clonidine to lidocaine for retrobulbar block causes a decrease in intraocular pressure, a sedative effect, and an increased duration of analgesia and akinesia, with relatively stable hemodynamic parameters.
