Long-term, open catheterization of the spinal subarachnoid space for continuous infusion of narcotic and bupivacaine in patients with "refractory" cancer pain. A technique of catheterization and its problems and complications.

The technique of long-term, open catheterization of the spinal subarachnoid space for infusion of analgesics in patients with refractory cancer pain is sparsely reported in the literature. We report on a technique using 18G Portex nylon catheters and 16G-17G Tuohy needles, and its problems and complications. One hundred fifty-seven catheters were inserted in 142 patients, in most of them (79%) under deep sedation and local anesthesia. Attempts were made to place the catheter tip as close to the painful segments as possible. The catheters were tunneled subcutaneously (87% of them paravertebrally, over the shoulder, and further parasternally to the third chondrocostal cartilage). The Luer connections of the catheters were fixed to the patients' skin with monofilament steel sutures of dimension 0 and connected to a bacterial filter. At the end of the procedure, 10 ml isotonic saline was injected intrathecally to prevent postspinal puncture headache. Absorbent and impermeable dressings were applied over the tunnel exit, catheter Luer connection and bacterial filter. Antibiotics were given on the day of insertion and 2 days thereafter. During the insertion procedure, the following problems and complications were encountered; two or more attempts before successful spinal-dural puncture (32%), accidental puncture of an extradural vessel (10%), difficult dural puncture (18%), absence of free dripping of cerebrospinal fluid (CSF) in spite of successful dural puncture (4%), blood-stained CSF (9%), radicular pain and paresthesiae (4%), difficult advancement of the catheter (6%), difficult tunneling (11%), and bleeding in the tunnel (0.7%).(ABSTRACT TRUNCATED AT 250 WORDS)

Continuous infusions of local anesthetics and narcotics for epidural analgesia in the management of labor.

It appears that complete analgesia for labor using epidural and subarachnoid opiates alone, with a minimum of side effects, remains an unfulfilled goal. However, the combination of extremely small doses of local anesthetics and opiate drugs seems to provide excellent analgesia with a minimum of side effects. This concept of combined opiates and local anesthetics corresponds to that of modern "balanced" general anesthesia, in which small amounts of several drugs are used to provide excellent anesthesia with a minimum of the side effects seen with large doses of any single drug. In my opinion, this "balanced" regional anesthesia holds great promise for the future, especially with the discovery of new drugs that produce spinal analgesia through a variety of mechanisms. These drugs include catecholamines, clonidine, GABA agonists, substance P antagonists, prostaglandin synthetase inhibitors, and many other drugs capable of altering neural transmission in such a way that analgesia results. Obviously, labor analgesia is one area in which these combinations will be explored extensively, and the next few years should be very exciting ones.

Pain management and weaning from narcotics and sedatives.

Over the last 10 years, there has been a fundamental change in physicians' attitudes toward analgesia and sedation in pediatrics. In this time, basic and clinical research have provided a wealth of information. In this paper we review important advances registered in the past year, including new molecular and physiological mechanisms of antinociception and sedation, behavioral and psychoemotional implications of pain, and advances in the clinical practice of pediatric analgesia and sedation. Fortunately, the attitude of physicians toward these matters has changed significantly and much more attention is now paid to the alleviation of pain and provision of adequate sedation. However, there remains, according to most estimates, incongruity between these advances and what is practiced clinically.
