    Advantages of bupivacaine over lignocaine in maxillary nerve and sphenopalatine ganglion block
    (NEUROLOGY INDIA, 1996) Rout, A; Suresh, L; Dash, PK
    Using Bupivacaine as local anaesthetic to block bilateral maxillary nerve and sphenopalatline ganglion for transsphenoidal excision of pituitary tumours, a prospective study in a series of 10 patients was carried out, This paper presents advantages of Bupivacaine over lignocaine block.

    Effect of temporary vascular occulsion during surgery of cerebral aneursyms
    (NEUROLOGY INDIA, 1996) Rout, D; Nambiar, U; Misra, BK; Rout, A
    Temporary vascular occulsion during surgery fog cerebral aneursyms has been slow to gain acceptance as an elective procedure, This study presents the outcome in 115 cases in whom temporary vascular occulsion was needed during aneurysmal surgery, Elective temporary clipping was used in 55 cases and emergency temporary vascular occulsion was performed in 60 cases, Judicious use of temporary clips did not increase the overall morbidity or mortality, Rescue temporary clipping as an emergency measure in the face of intraoperative rupture has a deleterious effect as against elective use on the immediate as well as long term outcome of the patient, Use of elective temporary clipping in conjunction with adequate cerebral protective measures is advocated in difficult cases to facilitate definitive clipping of the aneursym in order to improve the overall outcome.

    Prevention of hypertension during trans-sphenoidal surgery - The effect of bilateral maxillary nerve block with local anaesthetics
    (ACTA ANAESTHESIOLOGICA SCANDINAVICA, 1997)
    Background: Severe cardiovascular responses are known to occur during trans-sphenoidal excision of the pituitary gland despite adequate depth of anaesthesia. This study was undertaken to evaluate the effects of bilateral maxillary nerve block with local anaesthetics on the cardiovascular responses to various stimuli during this procedure.Methods: In a group of 32 patients, 5-10 mi of a mixture of bupivacaine 0.5% and lignocaine 2% (1:1) was injected in the pterygopalatine fossa after induction of general anaesthesia. Seven control group patients did not receive any nerve block. In all the patients, general anaesthesia was induced with thiopentone and maintained with nitrous oxide-oxygen, pentazocine, boluses of thiopentone and halothane. Pancuronium was used for neuromuscular blockade.Results: In both the groups, maximum hypertension occurred on opening the blades of the bivalve nasal speculum. In the study group, hypertensive response was significantly less following nasal infiltration with adrenaline containing solution (10.26% increase vs. 23.08% in the control group, P<0.05), nasal dissection (2.82% vs. 9.45%, P<0.01) and on application of the nasal speculum (14.93% vs. 35.16%, P<0.01). The effect on heart rate response was not significant.Conclusion: The described technique is a useful adjunct to general anaesthesia for suppressing the haemodynamic responses during trans-sphenoidal surgery.
