Analysis of narcotic analgesic usage in the treatment of postoperative pain.

We reviewed 526 medical records of surgical patients and interviewed 81 of these patients. We also sent questionnaires to house staff (57 of 97 responded) and nurses (70 of 142 responded) involved in the care of these patients. A substantial number of patients suffered at least moderate pain during the postoperative period despite analgesic medication. Patients received 70% of the maximal ordered analgesic dose in the first 24 hours. Physicians prescribed drugs in doses that were often inadequate and to be given at inflexible intervals. The optimal doses and duration of action of meperidine, as judged by the house staff and nurses, did not agree with the accepted pharmacologic profile of this drug.

A comparison of drug product information in four national compendia.

Four widely used compendia of prescribing information have been received to examine the way in which some drug companies recommend uses for several anti-inflammatory products and describe the major dangers in their use. The Physician's Desk Reference (PDR) cites the greatest absolute number of indications for steroids with systemic action, as well as the greatest number of contraindications, warnings and precautions, and adverse effects. The total number of precautions appearing in the PDR is three times the mean for the other compendia, and the number of adverse effects is four times the mean of the others. Together, these other compendia contain 70.5% of the number of words in the PDR. The PDR contains statements that are strongly directive for the physician and that do not appear in the other compendia. Regulatory and social differences may at least partially explain these discrepancies.

Attitudes of patients, housestaff, and nurses toward postoperative analgesic care.

A survey was carried out among housestaff and nurses involved with postoperative patient care to assess their knowledge of analgesics and their attitudes toward postoperative analgesic care. Only one-fifth of the respondents prescribed for complete pain relief. There were some misconceptions about adding other drugs to narcotic analgesics as well as fear of the addictive properties of these narcotics. The respondents lacked confidence about their knowledge of narcotic analgesics. Fear of respiratory depression was less prominent. Nine percent of the physicians and 31% of the nurses believed that response to a placebo indicates factitious pain. Fifty-four percent of the physicians and 74% of the nurses believed that patients receive adequate pain relief. Eighty-one patients were questioned on their beliefs about pain and its relief. Sixty-six of these were monitored postoperatively to assess the effectiveness of pain relief, which was judged by the authors to be ineffective (i.e., moderate to severe pain at the peak of analgesia) in 41%. Seventy-five percent of the patients reported that their overall postoperative pain relief had been adequate. There was no correlation between the amount of analgesic required postoperatively and either the degree to which patients believed pain builds character or the degree to which they rated themselves sensitive to pain. This study emphasizes the need for better and more comprehensive training of housestaff and nurses in analgesic care.

Antithrombin III contribution to cholestasis differential diagnosis: its correlation with one stage prothrombin time and factor V.

Levels of antithrombin III (AT III) measured by two different methods, Factor V (FV) and One Stage Prothrombin Time, have been studied in two groups of patients: 55 with chronic liver disease and 22 with extra hepatic cholestasis. Results show a statistically significant correlation between the decrease of AT III and FV in the first group, and the normality of these parameters (unrelated to One Stage Prothrombin Time) in the second group. Levels at AT III and FV correlate directly with the functional integrity of hepatic parenchyma, so they may help in the differential diagnosis of different types of cholestasis.
