The management of oral mexiletine and intravenous lidocaine to treat chronic painful symmetrical distal diabetic neuropathy.

Intravenous local anesthestics administered to patients with chronic pain have been shown to provide significant levels of systemic analgesia. Furthermore, oral mexiletine which is similar in structure has been demonstrated to be efficacious in the treatment of diabetic neuropathy. It is recommended that this combined form of treatment be considered with those patients whose diabetic neuropathy is resistant to more conventional forms of treatment.

Prevention of accidental injection of drugs in epidural tubing.

Numerous drugs have been injected into the epidural space unintentionally and different methods of prevention have been reported. This article describes the use of a needle cap as an available cost-effective alternative to prevent this mishap.

Epidural morphine pruritus reduction with hydroxyzine in parturients.

A majority of patients experience pruritus, nausea and/or emesis following epidural morphine administration post-cesarean section. Naloxone or diphenhydramine are commonly used to treat these side effects. Prevention or reduction in the incidence of side effects of epidural morphine is a clinical goal. The purpose of the study was to observe the efficacy of prophylactic administration of hydroxyzine on the incidence and severity of pruritus following the epidural administration of morphine in 40 patients who requested epidural morphine for postoperative pain relief. Group I (n = 20) received saline, while Group II (n = 20) received 50 mg of hydroxyzine ten minutes after the administration of 5 mg epidural morphine. Both solutions were administered by deep intramuscular injection in the thigh area. The results of this investigation demonstrated that hydroxyzine was efficacious in attenuating the incidence of severe pruritus.

Effect of position on the spread of buffered 2% chloroprocaine administered epidurally for the second stage of labor.

Increasing the pH of epidurally administered local anesthetics hastens their onset of action and improves the quality of neural blockade. The effect of body position on the epidural spread of alkalinized 2% chloroprocaine HCl for the second stage of labor has not been reported. We studied the epidural cephalad and caudad spread of 2% chloroprocaine buffered with sodium bicarbonate administered epidurally at the beginning of the second stage of labor. We randomly assigned 30 patients to one of two groups, each consisting of 15 patients. Group 1 received an epidural redose in the upright position, and the patients in group 2 received a redose in the supine position. There were no differences with respect to the sacral or cephalad spread. From the results of this study, we conclude that patients may receive epidurally administered 2% chloroprocaine late during the first stage of labor while in a supine position.

Maternal paraparesis after epidural anesthesia and cesarean section.

Continuous epidural infusion of local anesthetics containing epinephrine has become increasingly popular. This technique has been associated with few, if any, complications. We have presented a case of anterior spinal artery syndrome with paraparesis after continuous lumbar epidural infusion of an anesthetic during labor and subsequent emergency cesarean section.

A comparison of the incidence of pruritus following epidural opioid administration in the parturient.

Epidural morphine is associated with a high incidence of pruritus when used for pain control in the post-Caesarean section population. The purpose of this study was to compare the incidence of pruritus associated with epidural morphine, fentanyl, buprenorphine and butorphanol. Sixty healthy Caesarean section patients were studied in a double-blind randomized fashion. Patients were questioned at 1, 3, 12 and 24 hours postpartum for the incidence of pruritus. This study demonstrated that the incidence of pruritus was significantly higher following the use of epidural morphine and fentanyl. Even though epidural butorphanol and buprenorphine exhibited a low incidence of pruritus, their duration of analgesia was not long enough to make either attractive for single-dose administration.

The effect of pH-adjusted 2-chloroprocaine on the onset of epidural analgesia in pregnant patients in the lying and sitting position during the first stage of labor.

The purpose of this prospective, randomized, double-blind study was to compare the epidural onset time of 2% 2-chloroprocaine with pH-adjusted 2-chloroprocaine administered in either the sitting or supine position in pregnant patients during the first stage of labor. Patients in Groups I and III received the control solution in the sitting and supine position, respectively. Patients in Groups II and IV received the buffered solution in the sitting and supine position, respectively. The pH and pCO2 of the control and buffered solutions differed significantly. The pH and pCO2 of the control and buffered solutions were 4.38 +/- 0.01, 18.4 +/- 2.2 mm Hg and 7.70 +/- 0.04, 114.9 +/- 3.0 mmHg, respectively. A statistically significant reduction in the time of onset of analgesia in the pH-adjusted groups was noted. Groups I and II had onset times of 4 +/- 1.2 and 4.3 +/- 1.0, whereas Groups II and IV had onset times of 2.6 +/- 0.9 and 2.7 +/- 0.6 min., respectively. There were no intergroup differences in the cephalad spread of analgesia or duration of analgesia. Position had no effect on the onset of analgesia at the S2-3 dermatomes nor on the bilateral cephalad spread of the epidural study solutions. Our results indicate that a pregnant patient may be dosed in the lateral supine position without adversely affecting the caudad or cephalad spread of plain or pH-adjusted 2% 2-chloroprocaine, which is clinically important because the incidence of aortocaval compression is increased in the supine position when compared with the lateral supine position.(ABSTRACT TRUNCATED AT 250 WORDS)
