Abstract
BACKGROUND AND OBJECTIVES The performance of caudal injection (CI) has become a routine part of pediatric anesthesia. The intraoperative and immediate postoperative complications of CIs have been reported extensively. Although the long-term consequences of CI are unknown, they may include the development of epidermoid tumors in the spinal canal. Such tumors have been attributed to tissue coring (the process by which pieces of tissue are removed by a needle as it passes through the tissue) and the subdural deposition of such tissue. METHODS In this study, we examine the internal needle of 20-gauge i.v. cannulae from 50 CIs for evidence of tissue coring. RESULTS We found a total coring incidence of 54% (95% confidence interval = 40-68%). Epidermal tissue was present in 33% of the positive samples. Fat was present in 67% of the positive samples and bloody material in 26%. This study provides an estimate (with a 95% confidence interval) of the rate of coring during CI performed with hollow point needles. CONCLUSIONS These findings suggest that technical modifications may improve patient safety. The results also have implications for long-term follow-up of caudal anesthetics. Techniques for reducing the incidence of tissue coring during the performance of CI are discussed.

Abstract
UNLABELLED We report on a retrospective analysis of eight episodes of toxic methaemoglobinaemia in seven premature infants after the combined exposure to prilocaine by EMLA cream (12.5 mg prilocaine) and caudal anaesthesia (5.4-6.7 mg/kg prilocaine). The causative relationship between prilocaine and the infants' deterioration came to our attention through an anonymous voluntary incident-reporting system. The highest methaemoglobin concentration found was 30.6% (5.5 h after anaesthesia). All infants were symptomatic (mottled skin, paleness, cyanosis, poor peripheral perfusion) and two were exposed to unnecessary diagnostic and therapeutic procedures for unspecified deterioration in their conditions. Pharmacokinetic evaluation indicated a single compartment first-order elimination with a methaemoglobin half-life of 8 h. Normal levels (<1%) were reached 36 h after exposure to prilocaine. CONCLUSION Whereas local skin application of prilocaine to premature babies is safe, peridural administration is not because premature infants are more sensitive to methaemoglobin inducing agents and tolerate methaemoglobinaemia less well.

Abstract
A caudal block is currently performed in children. A randomized and double blind study including two dosages of fentanyl: 0.5 microgram.kg-1 (group I) and 1 micrograms.kg-1 (group II) in association with bupivacaine 0.25% at a dosage of 1 mL.kg-1 was carried out. Two groups of 25 children undergoing urogenital or orthopaedic surgery participated in this study. Analgesia and side effects were evaluated 24 hours postoperatively. Quality and duration of analgesia were similar in the two groups. Furthermore, recovery of anaesthesia was rapid and calm. The frequency of nausea and vomiting was respectively 24% and 20% in groups I and II and did not require any specific therapy. Therefore it appears that caudal block with bupivacaine 0.25% and fentanyl 0.5 microgram.kg-1 is a very satisfactory technique in children when indicated.

Abstract
We sought to determine the contemporary frequency of seizures, and the associated cardiovascular changes, resulting from local anesthetic-induced seizures in all patients undergoing brachial plexus, epidural, and caudal regional anesthetics. We investigated the following variables: development and treatment of seizure or cardiac arrest during the regional anesthetic, type of anesthetic (including local anesthetic used), gender, age, ASA physical status class and type of operation (elective or emergent). In addition, each patient who experienced a seizure underwent retrospective review of the acute event to determine the arterial blood pressure and heart rate changes accompanying the seizure, as well as details of the regional block technique. There was a significant difference between the rate of seizure development between epidural, brachia, and caudal anesthetics, with caudal > brachial > epidural. A significant difference was also noted in the rate of seizure development within types of brachial block, with supraclavicular and interscalene > axillary. No adverse cardiovascular, pulmonary or nervous system events were associated with any of the seizures, including the 16 patients who received bupivacaine blocks. The frequency of local anesthetic-induced seizures stratified by block type has a wide range, and cardiovascular collapse after bupivacaine-associated seizure has a low incidence.

Abstract
A retrospective multicentre study of the complications observed after regional anaesthesia in children was undertaken in 1991 at the request of the association of Anesthésistes-Réanimateurs Pédiatriques d'Expression Française (ADARPEF). The incidence of accidents seen in the study was comparable to that found in the literature. Five cases which were exceptional due to the severity of the sequelae have been analysed separately. Different pathophysiological mechanisms are proposed.

Abstract
Caudal loco regional anesthesia is a quite simple and secure procedure. That is a prospective study made on seventy children operated in orthopaedics, urology and general surgery below the ombilicus. The caudal epidural anesthesia followed a general anesthesia in all seventy cases and brought relief in terms of analgesia, even for those painful surgical procedures. The good post operative status with only some minor complications leads us to use widespreadly caudal epidural.

Abstract
The above account concerns 50 cases of caudal anaesthesia with 2% plain lidocaine (i.e. without adrenaline), after a preliminary and a complementary general anaesthesia for surgical operations in the infra umbilical region not exceeding one hour in duration. The anaesthetic effect was as rapid as the recovery from it. The analgesic effect was excellent in 98% of cases. No per or post operative complications were observed with the employment of this technique. The authors recommend that this technique should be employed more frequently in day case pediatric surgery.

Abstract
Adult caudal blockade has fallen from favor in the anesthesia community. The majority of anesthesia providers now use lumbar epidurals and spinals for surgeries that can be done with caudals. Many claim the procedure is difficult to perform and the outcome of the block is unpredictable. Caudal anesthesia has distinct advantages over lumbar epidurals and spinals and can be done with confidence by anesthetists who are willing to learn the anatomy, basic skills, and limitations entailed in this lost technique.

Abstract
One hundred children aged 1 to 15 years were randomly allocated to two equal groups. All underwent cold orthopedic surgery to the lower limb, of more than 1 hour's duration with a standard anesthetic technique. One group received caudal bupivacaine 0.25%, 0.7 mL/kg, and one group acted as controls. There were no cases of fecal incontinence in the theater complex but urinary incontinence in the immediate recovery phase increased from 14% in the control group to 34% in the caudal group (P < .05). The caudal block had a duration of effect lasting 5 to 6 hours, and provided better recovery room analgesia (P < .01). The advantages for the child are discussed.

Abstract
Sixteen children, aged 2 to 5 years and ranked ASA 1, were included in this study assessing gastro-oesophageal reflux occurring under halothane anaesthesia, before and during, caudal anaesthesia. They were scheduled for surgery below the umbilicus lasting 1 to 5 h. After premedication with oral hydroxyzine (2 mg.kg-1) and intravenous atropine (10 micrograms.kg-1), induction was carried out with 3% halothane. A gastro-oesophageal pH probe was inserted via the nose after calibration at 37 degrees C. A neutral pH for the oesophageal electrode and an acid pH for the gastric one demonstrated the correct position of the probe. The pH was then registered every 4 s. The probe was left in situ until the patient left the recovery room. The caudal anaesthesia catheter was then inserted with the patient lying on his left side. Caudal anaesthesia was began with 2.5 mg.kg-1 of plain bupivacaine and 5 mg.kg-1 of plain lidocaine. When the patient was lying supine again, narcosis was maintained with 0.5% halothane and 50% nitrous oxide. A dose of 1.5 mg.kg-1 of bupivacaine was injected every 30 to 45 min. None of the children displayed any respiratory signs (coughing, dyspnoea, bronchospasm, cyanosis) during the combined anaesthetic. Two episodes of asymptomatic gastro-oesophageal reflux were revealed by this method, one lasting 7 minutes and occurring during insertion of the caudal catheter, and the other, lasting 4 minutes, during recovery. There were no pulmonary sequels. There was excellent respiratory and haemodynamic stability throughout. The two episodes seemed to have been triggered off by rapid displacement of the patient and too deep an anaesthetic.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Present day trainee anaesthetists could be forgiven if they finished their anaesthetic training believing that caudal anaesthesia in obstetrics is not only unnecessary, but dangerous and a relic of the past. Many anaesthetic texts teach applications and techniques which are little or no advance on the teachings of Hingson and Edwards in 1942 and reflect nothing of the true value and application of this valuable block. This paper presents a critical review of these texts and of the results of the use of the block in a busy obstetric unit.

Abstract
The value of combining morphine with bupivacaine for caudal analgesia was investigated. Thirty children, undergoing orchidopexy, received a caudal block of 0.125% bupivacaine with or without morphine 0.05 mg kg-1. Analgesia, side-effects, ventilatory frequency and oxygen saturation (SaO2) were recorded after operation. None of the 15 patients receiving the bupivacaine-morphine mixture required post-operative opioids, whereas eight of 15 patients receiving bupivacaine alone needed additional opioid analgesia. The incidence of side effects after surgery was similar for the two groups and there was no detectable difference in ventilatory frequency or SaO2.

Abstract
Forty-three children for day case inguinal herniotomy under general anaesthesia were assigned randomly to receive either 1 ml/kg caudal bupivacaine 0.25% or rectal diclofenac 0.25 mg/kg intra-operatively to provide postoperative analgesia. Pain and demeanour were assessed by an observer in the early postoperative period after operation and by questionnaire for the parents over the first 24 hours. Caudal bupivacaine provided more pain-free patients at first but later the incidence of pain was similar in the two treatment groups. Rectal diclofenac is a useful alternative to caudal blockade in this group of patients.
