Providing safe and effective analgesia to laboring parturients presents a challenge to anesthesia providers in small hospitals. The necessary time commitment and additional staff needed to provide coverage for the obstetrical area can strain resources. Offering the spinal opioid block as the first choice for labor analgesia and the combined spinal epidural block in selected cases permits a labor anesthesia service to address the needs of the community hospital. ⋯ The combined spinal epidural block offers the advantages of spinal opioid analgesia but with the flexibility of having an epidural catheter in place. The epidural catheter can be dosed intermittently for parturients in whom labor is prolonged, who require surgical manipulation for vaginal delivery, or who require cesarean section for delivery. By offering both blocks to laboring parturients, the appropriate block can be applied in each situation.

Michael L. Millenson's well-documented book, Demanding Medical Excellence: Doctors and Accountability in the Information Age, is a wake up call to both medicine and nursing for somewhat different reasons. Millenson decries the lack of scientific-based medical practice and medicine's failure to wake up due to its own historical studies. ⋯ Consumers of MEDLINE should be aware of this problem and be prepared to question the validity of research prior to adopting their conclusions. In the development of "best practices," flawed research may be as bad as personal biases and flawed memories. The potential adverse implications of flawed research for scientifically (evidenced) based practice and for health policy decisions by government and health payers with regard to the delivery of health services and its reimbursement requires that all involved do a better job of assuring that only valid, methodologically sound, and unbiased research is published, is included in the MEDLINE database, and is used in the care afforded to people in need.

Clinical Trial Controlled Clinical Trial
Intradermal bacteriostatic 0.9% sodium chloride containing the preservative benzyl alcohol compared with intradermal lidocaine hydrochloride 1% for attenuation of intravenous cannulation pain.
This study compared the efficacy of a common medication diluent, bacteriostatic 0.9% sodium chloride containing the preservative benzyl alcohol with lidocaine hydrochloride 1% as an intradermal pretreatment for the relief of pain associated with intravenous cannulation. Forty adult presurgical patients requiring two large bore intravenous catheters were used. They served as their own controls. ⋯ A paired t test was used to compare differences in VAS scores with the pretreatment bacteriostatic 0.9% sodium chloride containing the preservative benzyl alcohol with the pretreatment lidocaine hydrochloride 1%. Analysis of the data revealed no significant difference in the report of perceived pain of intravenous cannulation based on the intradermal pretreatment. These findings suggest that intradermal bacteriostatic 0.9% sodium chloride containing the preservative benzyl alcohol is as effective as intradermal lidocaine hydrochloride 1% in the attenuation of intravenous cannulation pain.

Randomized Controlled Trial Clinical Trial
Evaluation of the effects of the addition of morphine sulfate to a standard Bier block solution in peripheral arm surgery.
The purpose of this study was to analyze postoperative pain differences in patients undergoing peripheral arm surgery. Differences between patients' perceived pain who received 2 mg of morphine sulfate added to the standard Bier block solution and the standard Bier block solution without morphine were studied. A quasi-experimental nonequivalent control group design was utilized. ⋯ A larger sample may have yielded different results. Many issues remain undecided regarding the potential role of opioids in various regional anesthetic techniques. Further studies are warranted to investigate the peripheral effects of opioids and to understand the mechanisms of action of opioid analgesics at peripheral sites.
