Patients receiving intraspinal opiates should be monitored in the intensive care unit for at least 24 hours to prevent potentially lethal outcomes. These include respiratory depression caused by sequestration of the morphine in the cerebrospinal fluid and migration of epidural catheters in the subarachnoid or intravascular space. At this time, most hospitals are not equipped or staffed adequately to guarantee the safety of these patients outside the intensive care unit.

Most patients receiving spinal narcotics can be monitored adequately by well-trained nurses on postoperative or postdelivery wards. Patients at high risk (e.g., those with preexisting lung disease or many elderly patients) do need monitoring in the intensive care unit. Also requiring special monitoring are patients for whom epidural narcotics alone will not cover their pain, such as young patients with multiple trauma. Patients without these restrictions, however, can be monitored successfully outside the intensive care unit, although the dose of epidural narcotic should be kept as low as possible.

The purpose of this study was to determine if patient-controlled analgesia (PCA) is an effective method of postoperative pain relief for children. Fifteen general surgery patients, aged 11 to 18 years, were treated for pain with PCA. ⋯ The average amount of medication administered by PCA was compared with the amount given to similar group of children treated by traditional administration; overall, the PCA group received less morphine than the traditional group. This study indicates that PCA is a valuable addition to pain management for the pediatric patient.

Comparative Study
The subjective experience of acute pain. An assessment of the utility of 10 indices.
Sixty-nine postoperative patients indicated the severity of their pain using eight measures designed to assess pain intensity and two designed to measure pain affect. The utility and validity of the 10 measures were evaluated according to two criteria: (a) the magnitude of the relationship between each scale and a linear combination of the pain measures, and (b) relative rates of incorrect responding. ⋯ The 11-point Box Scale (BS-11) of pain intensity demonstrated the strongest relationship to a linear combination of all of the measures employed and was responded to correctly by each subject in the sample. All else being equal, these results suggest that the BS-11 scale may be the most useful clinical index of pain intensity among postoperative patients.

Randomized Controlled Trial Clinical Trial
Comparison of one technique of patient-controlled postoperative analgesia with intramuscular meperidine.
We have compared analgesic requirements, perceived pain, and self-assessment of 'health locus of control' for 72 h in 88 subjects after cholecystectomy, randomized to either a standard technique of self-administration of meperidine (patient-controlled analgesia, PCA) or to intramuscular injections on demand (i.m.). Multivariate analysis revealed no statistical differences between group scores for pain (over any 24 h period) and only minor differences in total meperidine administered. ⋯ Assessment of 'health locus of control' did not show any marked changes. Analysis of patient questionnaires suggests more enthusiasm for patient-controlled analgesia, but in this study, it was difficult to clearly demonstrate any significant advantage for pain management or amount of opiate administered.
