Patients want safe and effective analgesia. Our goal is to prevent postoperative pain in an efficient and cost effective manner. For most patients, the pain can be managed using simple, non-invasive and inexpensive analgesic techniques. ⋯ There will be pressure to discharge patients as soon as they are able to take oral medications. Outpatient analgesia is the oldest and most widespread form of patient-controlled analgesia--We already have the knowledge and the analgesics necessary to prevent postoperative pain. What we need now is logical, rational, and universal application of this information.

Selective dorsal rhizotomy (SDR) is a neurosurgical procedure used for treating lower extremity spasticity in patients with cerebral palsy. The purpose of this paper is to present a review of our institution's first three years' experience with postoperative pain and spasticity management in patients who have undergone SDR. The medical records of the 55 patients who had an SDR during the study period were reviewed. ⋯ All patients received continuous cardiorespiratory monitoring as well as frequent nursing assessment. There were no episodes of postoperative apnoea or excessive sedation. We have found the use of continuous infusions of morphine and midazolam, along with adjunct ketorolac, to be effective in treating postoperative pain and muscle spasms following SDR.

Two paediatric cases are reported in which unexpected, life-threatening arrhythmias occurred. Routine induction of general anaesthesia with thiopentone, 5 mg.kg-1, in one and with halothane in the other, and succinylcholine 1.25-1.5 mg.kg-1 i.v. was followed by the development of wide complex tachyarrhythmia with hypotension in the first case and asystole in the second case despite pre-treatment with atropine in both cases. The first patient was resuscitated with tracheal intubation, 100% oxygen, manual ventilation and intravenous lidocaine and bicarbonate. ⋯ Subsequent investigations revealed the presence of a dystrophin-deficient muscular dystrophy, Duchenne muscular dystrophy and Becker muscular dystrophy respectively, previously unsuspected, in both patients. The aetiology of the observed arrhythmias was presumably hyperkalaemia, secondary to succinylcholine-induced rhabdomyolysis. It is suggested that when faced with sudden, life-threatening arrhythmias following succinylcholine at induction of anaesthesia for paediatric patients, clinicians should include occult myopathy in the differential diagnosis, and thus consider the aggressive management of hyperkalaemia in addition to basic resuscitative efforts.
