I. Douglas et D. Bush, The use of patient-controlled boluses of local anaesthetic via a psoas sheath catheter in the management of malignant pain, PAIN, 82(1), 1999, pp. 105-107
Patients who develop malignant infiltration of the psoas muscle and the lum
bar plexus often experience a severe complex pain syndrome characterised by
deep somatic pain, neuropathic pain and psoas spasm. Conventional analgesi
c regimes may not relieve these symptoms adequately. We describe the use of
patient-controlled boluses of local anaesthetic via a psoas sheath cathete
r in this scenario. The recent availability of portable infusion pumps with
the capability to deliver large volume boluses with long lockout times mad
e this intervention possible and allowed the patient to be discharged home
with effective relief of pain. (C) 1999 International Association for the S
