Hyperkalaemia: a complication of warm heart surgery.

A case is presented of hyperkalaemia (13.6 mEq.L-1) occurring during cardiopulmonary bypass using warm blood cardioplegia (K+ 40-60 mEq.L-1). Treatment with epinephrine, calcium chloride, sodium bicarbonate, and furosemide reduced K+ to 6.5 mEq.L-1 within 30 min and myocardial performance was enhanced with amrinone and cardiac rhythm was controlled with A-V segmental pacing. It is believed that the hyperkalaemia resulted from a combination of the surgical procedure (mitral valve replacement) and the use of warm cardioplegia. The purpose of this report is to increase the awareness of the possibility of hyperkalaemia with warm cardioplegia and to describe a successful therapeutic regimen.

Pain management of the oncologic patient.

After the first 5 years of life, cancer is one of the three most common causes of death. Most investigations of cancer pain have shown that 50-70% of patients suffer needlessly. Pain may be due to the tumor or a co-existant benign pain syndrome. Methods of pain management include: 1) neurolytic blockade: stellate ganglion block, celiac plexus block, lumbar sympathetic block, epidural phenol, subarachnoid neurolysis; and 2) non-pharmacologic methods: radiofrequency thermocoagulation lumbar sympathectomy, transcutaneous nerve stimulation (TENS), dorsal column stimulation (DCS). In summary, we utilize every possible combination of therapeutic modalities for cancer pain management. With so many safe procedures available, we encourage the primary physician to refer patients early in their disease process. Neurolytic procedures should be performed prior to initiation of high dose narcotic therapy, radiation, chemotherapy, and surgery when possible.

Loss of consciousness after emergence from anaesthesia. A case of suspected micturition syncope.

A case of postanaesthesia micturition syncope with respiratory arrest is described. If syncope occurs, the temporary myocardial ischaemia and cerebral hypoperfusion may increase anaesthetic risk in the marginally compensated patient. The loss of airway protection during the syncopal period is also a cause of concern. We recommend the use of an indwelling bladder catheter during any prolonged surgical procedure.

Percutaneous dorsal column stimulator for chronic pain control.

This is a retrospective review of 26 patients with chronic intractable pain in which dorsal column stimulation was used as a salvage procedure. On follow-up of 12 to 42.7 months, 21 of the patients had diminished narcotic usage. Seventeen patients subjectively rated their pain relief as good to excellent. Another five patients reported some relief of pain. Two-thirds of the patients reported an increase in their ability to perform daily activities such as walking, stair climbing, and time spent sitting. There are still many technical problems that plague this procedure, as evidenced by a very high technical complication rate of lead migration and lead breakage. Whether or not results diminish over long-term follow-up remains to be seen.
