Abstract. In a prospective, randomized study the duration and effectiveness of four different regimens of PCB were studied: Bupivacaine both with and without adrenalin, and chloroprocaine with and without adrenalin. The pain relief was immediate and almost complete in most patients in all four treatment groups. The duration of the effect of bupivacaine was the same whether adrenalin was added or not. The labors were significantly prolonged with adrenalin, however. The duration of the effect of… Expand

Cervical conization is done for pre-cancer disease. The procedure is performed with local anesthesia and general anesthesia. Local anesthesia is given by paracervical block, and… Expand

Pain control after percutaneous biliary drainage: local infiltration with bupivacaine and epinephrine.
The ability of local anesthetics to control pain at the catheter site was discovered by chance, after a patient complained that narcotics made her dysphoric but did not actually relieve the pain. Expand
Paracervical block for labor analgesia: a brief historic review.

Overall, it appears that the incidence of postparacervical block fetal bradycardia is the most significant side effect with a reported incidence ranging from 0% to approximately 40%, and there are too few trials with too few patients. Expand
Epinephrine Enhances Analgesia Produced by Epidural Bupivacaine during Labor
It is concluded that epinephrine 1:300,000 modestly but statistically significantly improves the analgesic efficacy of epidurally administered 0.25% bupivacaine during labor. Expand
Letter to the Editor
In their recent articles, Belfrage and Floberg (1) and Nesheim (2) concluded that the perfect local anesthetic agent for obstetrical anesthesia has not been identified and that chloroprocaine is notExpand
Paracervical Block‐A Viable Alternative for Labor Pain Relief?
Background. Two hundred and forty‐eight consecutive deliveries with a 0.25% bupivacaine paracervical block (PCB) using a superficial injection technique were studied prospectively during the progressExpand
Effect of Labor Epidural Analgesia With Hydromorphone on Neonatal Neurobehavior and Breastfeeding Behavior in the First 24 Hours of Life
Data indicate that, by itself, epidural analgesia with hydromorphone does not decrease effectiveness of breastfeeding behaviors, and the presence of multiple stressful events or interventions contributes to breastfeeding difficulties and necessitate intensive help from the nurse to achieve success in breastfeeding.

Local anaesthetic nerve block for pain management in labour.
Local anaesthetic nerve blocks are more effective than placebo, opioid and non-opioid analgesia for pain management in labour based on RCTs of unclear quality and limited numbers. Expand
Effects of bupivacaine and calcium antagonists on human uterine arteries in pregnant and non‐pregnant women
The bupivacaine‐induced vasoconstriction on uterine arteries from pregnant and non‐pregnant women was effectively reduced by two different calcium antagonists, verapamil and nifedipine. Expand

Le bloc paracervical permet d'obtenir une analgesie lors de la premiere phase du travail andalgesie et peut constituer une alternative a l'anesthesie peridurale dans la methode de reference. Expand


Paracervical block with low doses of chloroprocaine. Fetal and maternal effects.
Results of 261 paracervical blocks done with a dose of 12 ml of 1% chloroprocaine hydrochloride solution containing 1:200,000 epinephrine were recorded and one fetus died owing to multiple congenital anomalies. Expand
The use of paracervical nerve block anaesthesia in labour
It is concluded that the procedure has a useful place in obstetrics, but should only be used in selected cases and avoided where placental insufficiency is suspected or signs of foetal distress are present. Expand
The introduction of a longer acting anaesthetic agent, Bupivacaine, has resulted in an increased duration of effect and enhanced the value of the method, and the results accord with the findings of Yates (1967) and demonstrate an advantage over the other methods. Expand
Paracervical Block with 2‐Chloroprocaine
It is concluded that paracervical block using 2CP is an effective though short-acting method of pain relief which, when properly monitored, is safe for both mother and fetus. Expand
Paracervical block with bupivacaine 0.25 per cent.
The technique of paracervical block and its use in labour have been described and discussed by several authors (Kobak, and Sadove, 1961; Cooper and Chassar Moir, 1963; Pitkin and Goddard, 1963). TheExpand
Prolonging paracervical block anesthesia: addition of dextran to 2-chloroprocaine.
The pain relief provided by a single PCB with 2-CP in dextran is still relatively short and would not persist throughout the active phase of labor in most parturient women. Expand
Neurobehavioral response of infants after paracervical block during labour
Arterial and venous pO2, pCO2 and pH from the umbilical cord showed no differences between the groups, and no clinically significant differences could be detected between the two groups. Expand
