An acute pain service (APS) was set up to improve pain management after operation. We attempted to reduce the length of stay in the intensive care unit (ICU) of patients undergoing major surgery and to improve their homeostasis and rehabilitation using a multimodal approach (pain relief, stress reduction, early extubation). Patient-controlled epidural analgesia (PCEA) was a keystone of this approach. ⋯ In the case of PCEA, the quality of pain relief, vigilance and satisfaction were superior compared with the PCIA method, which resulted in greater sedation and nausea. Although personal supervision was higher for the PCEA-treated patients, cost analysis revealed final savings of Euro 91,620 for the year 1998 obviating the need for an ICU stay totalling 433 days. Provided that PCEA is part of a fast-track protocol employing early tracheal extubation and optimal perioperative management, the associated initial higher costs will be recouped by the benefits to patients of better pain relief after surgery and fewer days subsequently spent in the ITU.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia after peripheral nerve block for podiatric surgery: clinical efficacy and chemical stability of lidocaine alone versus lidocaine plus ketorolac.
The purpose of this study was to determine whether the addition of ketorolac tromethamine to local anesthesia for ankle block alters the quality or duration of analgesia after podiatric surgery. The second aim was to determine the chemical stability of ketorolac tromethamine when added to local anesthetic solutions. ⋯ The addition of ketorolac to lidocaine for ankle block contributed to longer duration and better quality analgesia after foot surgery compared with plain 1.73% lidocaine or 1.73% lidocaine plus intravenous ketorolac. The ethanol vehicle is unlikely responsible for the analgesic effects of ketorolac. Ketorolac retains its chemical stability when placed in local solutions of lidocaine or bupivacaine.

The neurolytic celiac plexus block (NCPB) has been recommended for pain relief in patients with upper abdominal cancer by the WHO Cancer Pain Relief Program. In this article, we review the indications, techniques, and adverse effects of NCPB based on the previous findings in the literature and our own experience of 142 NCPBs during the past 11 years. No well-validated indication criteria for the NCPB have been available from invasive trials or non-invasive pain evaluations. ⋯ The diarrhea may counteract the morphine-induced constipation. NCPB relieves visceral pain in upper abdominal cancer with no serious adverse effects. We recommend this procedure to improve the quality of life of the patients suffering from abdominal cancer pain.

Clinical TrialCutaneous sympathetic vasoconstrictor reflexes for the evaluation of interscalene brachial plexus block.
Although signs of sympathetic blockade following interscalene brachial plexus block include Horner's syndrome, increased skin temperature and vasodilatation, the degree of sympathetic blockade is not easily determined. The aim of this study was, therefore, to use activation of cutaneous finger pad vasoconstrictor reflexes for description and quantification of the degree of sympathetic blockade following unilateral interscalene brachial plexus block. ⋯ Interscalene brachial plexus block reduces regional sympathetic nervous activity, illustrated by increases in skin blood flow, skin temperature and attenuated vasoconstrictor responses to an inspiratory gasp. The inspiratory gasp vasoconstrictive response is a powerful and sensitive indicator for monitoring the sympathetic blockade following interscalene brachial plexus block.

Randomized Controlled Trial Clinical TrialAlkalinized lidocaine and bupivacaine with hyaluronidase for sub-tenon's ophthalmic block.
Alkalinization of local anesthetics has been shown to decrease the onset and prolong the duration of block for extraconal and intraconal application in ocular surgery. The objective of this study is to determine if alkalinization is also effective in sub-Tenon's block when hyaluronidase is added to the drug mixture. ⋯ pH adjustment of the local anesthetic mixture of lidocaine, bupivacaine, and hyaluronidase offered no additional benefit in sub-Tenon's technique in ocular procedures.
