Randomized Controlled Trial Comparative StudyComparative evaluation of myolaxin and EMLA cream for attenuation of venous cannulation pain: a prospective, randomised, double blind study.
We evaluated the efficacy of topical Myolaxin (capsaican ointment, Geno, Mumbai) ointment over EMLA (eutectic mixture of lignocaine, prilocaine; Neon, Goa) cream for attenuating venous cannulation pain in this prospective, randomised, double blind study. Sixty adult patients undergoing elective laparoscopic cholecystectomy were randomly assigned into two equal groups. Group I (EMLA) received EMLA cream, whereas Group II (Myolaxin) received Myolaxin ointment. ⋯ The incidence of venous cannulation pain was similar between groups: in the EMLA group 65% (18/28) compared to 67% (20/30) in the Myolaxin group (P=0.19). The severity of pain (median VAS with inter quartile range) was also similar between the groups: in the EMLA group 1.5 (3) compared to 1.5 (2) in the Myolaxin group (P=0.46). As the topical application of Myolaxin ointment is cheaper than EMLA and has similar efficacy, it may be a suitable alternative for reducing the incidence and severity of venous cannulation pain.

Case ReportsRecurrence of focal seizure activity in an infant during induction of anaesthesia with sevoflurane.
A three-month-old male infant, previously diagnosed with seizures with a focal origin induced by hypocalcaemia secondary to hypoparathyroidism, presented for right cataract surgery. The hypocalcaemia and seizure activity had resolved with medical therapy, with normal calcium levels and no seizures for a month. Anaesthesia with halothane and isoflurane for left cataract surgery two days previously had been uneventful. ⋯ The patient had normal calcium levels at the time of surgery. It appears likely that sevoflurane had triggered seizure activity in the apparently controlled focus. The potential for sevoflurane to induce epileptogenic activity in patients with reduced seizure threshold is discussed.

Case ReportsInspiratory muscle training to enhance weaning from mechanical ventilation.
This report describes the use of specific inspiratory muscle training to enhance weaning from mechanical ventilation in a patient who had failed conventional weaning strategies. A 79-year-old man remained ventilator-dependent 17 days following laparotomy. ⋯ By day 27, mechanical ventilation was no longer required. Inspiratory muscle training can be implemented effectively in the difficult to wean patient and should be considered for patients who have failed conventional weaning strategies.

Review Case ReportsLemierre's syndrome with septic shock caused by Fusobacterium necrophorum.
Fusobacterium necrophorum infections are rare. We report a 15-year-old male who presented with tachycardia, nausea, vomiting, diarrhoea and ankle pain. He rapidly deteriorated requiring ventilation and vasopressors. ⋯ Fusobacterium necrophorum was identified in blood culture on day nine. The patient recovered with antibiotics and surgical interventions for empyema and septic arthritis. Fusobacterium necrophorum should be a suspected pathogen in septic shock complicated by metastatic abscess formation.
