Pain in critically ill and injured pediatric patients may go unrecognized and undertreated since children often suffer silently and caretakers are often fearful to intervene aggressively to alleviate pain. Methods are now readily available to relieve pain in the vast majority of ICU patients. ⋯ This can be achieved by the use of continuous intravenous infusions of opioids, PCA, or epidural administration of local anesthetics or opioids. Flexibility is essential so that the appropriate technique or agent can be selected for a particular pediatric ICU patient.

Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled versus conventional analgesia for postsurgical pain relief in adolescents.
We performed a randomized nonblinded, cross-over comparison of patient-controlled analgesia (PCA) with conventional intramuscular analgesia in 10 adolescents (13-18 years) undergoing spinal fusion for idiopathic scoliosis. PCA use afforded more effective pain control (p < 0.02) on a 10-point linear pain intensity scale than did intramuscular injections, while causing an equal amount of sedation and no side effects. PCA appears to be a promising technique for providing postoperative pain relief in this group of adolescents. Further studies are needed to define its role for other pediatric conditions.

Randomized Controlled Trial Comparative Study Clinical Trial[Patient-controlled analgesia: effect of adding continuous infusion of morphine].
This double blind study aimed to assess the effects of a continuous intravenous (i.v.) infusion of morphine added to an intermittent bolus patient controlled analgesia on morphine demand and related side-effects. Patients scheduled for abdominal and thoracic surgery (ASA 2 or 3) were randomly allocated postoperatively to three groups (n = 10 each): group 1 were given i.v. boluses of 2 mg of morphine (lockout interval = 15 min); the other two groups were given the same boluses as well as a continuous i.v. infusion of either 1 mg.kg-1 of morphine (group 2) or 2 mg.kg-1 (group 3). Pain was assessed with a visual analog scale before starting analgesia, and after 1, 2, 3, 4, 8, 16, 24 and 36 h. ⋯ Total amounts of morphine were higher in groups 2 (56.8 +/- 23.8 mg) and 3 (116.2 +/- 41.8 mg) compared with group 1 (38.2 +/- 17.8 mg) (p < 0.05). Morphine administration was stopped in 5 patients in group 3 and in 1 in group 2 because PaCO2 had risen to more than 45 mmHg. Therefore, a continuous i.v. infusion is not required in patients receiving PCA, all the more so as this has deleterious respiratory effects.

Review[Patient-controlled analgesia by the peridural route and classical methods of analgesia].
Patient controlled analgesia was developed to compare drug effects. Later its psychological implications were studied. Drug administration by intravenous or epidural injection has been used. ⋯ Simultaneous use of opioids and anti-inflammatory drugs enhances the analgesic effects. For pain relief in childbirth, opioids need to be combined with local anaesthetics for best results. Little has been achieved by patient controlled analgesia in the treatment of chronic pain.
