    BACKGROUND: It is well documented that surgery is associated with increased anxiety, which has an adverse impact on patient\u27s outcome. This study was designed to assess the anxiolytic effect of midazolam in pre-anaesthetic medication by using clinical and platelet aggregation profiles.METHODS: Sixty ASA I and II female patients aged between 35 and 60 years undergoing elective abdominal hysterectomy were randomly divided into two equal groups. Group I received placebo as pre-medication while group II received 0.15 mg/kg midazolam as pre-medication 1 hour preoperatively. They were monitored for visual analogue scale (VAS) for anxiety, observer\u27s anxiety criteria, sedation score, blood pressure, heart rate and platelet aggregation profile immediately before and 1 hour after pre-medication.RESULTS: There was statistically significant difference with respect to VAS of anxiety, observer\u27s anxiety criteria, sedation scores, systolic and diastolic blood pressure (

    <p>Abstract</p> <p>Background</p> <p>Sub-Tenon's anaesthetic is effective and reliable in producing both akinesia and anaesthesia for cataract surgery. Our clinical experience indicates that it is sometimes necessary when absolute akinesia is required during surgery to augment the block with 1–2 ml of local anaesthetic. Hypothesis was that after first injection some of the volume injected may spill out and before second injection the effect of hyaluronidase has taken place and second volume injectate will have desired effect.</p> <p>Methods</p> <p>A prospective, randomised, control trial in which patients were randomly allocated to one of two groups. In group 1, single injection of 5 ml of local anaesthetic was injected. In group 2, 3 ml of the same anaesthetic solution was injected followed by application of gentle orbital pressure for 2 minutes. A further 2 ml of the same anaesthetic solution was injected through the same conjunctival incision. Measurement of movement in four quadrants of eye was done by the surgeon at 3 and 6 minutes. Intraocular pressure, chemosis, and subconjuctival haemorrhage were also measured.</p> <p>Results</p> <p>Significant differences at 3 minutes between groups for overall movement, medial, superior, and lateral quadrants occurred. At 6 minutes no significant group differences emerged for the overall movement or for any of four quadrants.</p> <p>Conclusion</p> <p>Single injection of local anaesthesia for sub-Tenon's block with mixture of lignocaine with adrenaline, bupivacaine and hyaluronidase was found to be superior to provide akinesia of ocular muscles compared to divided dose given by two injections. No difference in groups in terms of haemorrhage, chemosis, patient's satisfaction and intraocular pressure was found.</p> <p>Trial registration</p> <p>Trial registration no-ISRCTN73431052</p
