One hundred day surgical patients undergoing first trimester termination of pregnancy were randomly allocated to receive either 150 ml of clear fluid 1.5-2 hours before anaesthesia or to remain fasted from midnight the night before. Patients were anaesthetised using a total intravenous technique which consisted of propofol and alfentanil. No adverse intra-operative events were noted in either group. There were no significant differences in immediate recovery time, or pain, nausea and headache scores at 30 or 120 minutes following recovery. The fasted group had less pain (p less than 0.05) at 60 minutes after recovery than the fluid group, although the mean pain scores in both groups were low. Eighty two per cent of the patients returned questionnaires about pain, nausea and headache scores on arriving home, and at 12 and 24 hours after surgery. There were no significant differences between the two groups. In conclusion, pain, nausea and headache scores are low following total intravenous anaesthesia with propofol and alfentanil for termination of pregnancy and these were unaffected by the administration of 150 ml of clear fluid given approximately 1.5 hours pre-operatively.

Sixty-nine patients who underwent transurethral resection of the prostate under subarachnoid anaesthesia were studied. They were randomly allocated to either an early mobilisation group (group A, 30 patients), or a 24 hour bed rest group (group B, 39 patients). The incidence and severity of postspinal headache were assessed in each patient at 24, 48 and 72 hours. The incidence of headache in group B was significantly higher when compared with group A at 48 and 72 hours postoperatively (p less than 0.025 and p less than 0.01, respectively). The total incidence of headache throughout the 72 hours was also significantly higher in group B (p less than 0.01). Regarding the severity of headache the two groups did not differ significantly. Therefore, bed rest is not recommended as a prophylactic measure for postspinal headache.

This is a review of literature from 1943 to mid-1989 on the postdural puncture headache. The article looks at the currently held thoughts on the cause, prevention, and treatments of this second most frequent side effect of spinal anesthesia. Postdural puncture headache (PDPH) is caused by vascular distension within the nondistensible cranium following the leakage of cerebral spinal fluid (CSF) into the epidural space. Prevention of PDPH can be accomplished by using small-gauge needles and possibly by using the lateral approach, as opposed to the midline approach. Luck plays a big part, because if the needle punctures a thicker portion of the dura, there is a reduced chance of PDPH. Epidural saline injection is effective only if it is used as a continuous infusion for 24 hours. The usefulness of caffeine sodium benzoate with a 70-80% success rate and epidural blood patching with a 90%-plus success rate are discussed.

An elongated styloid process may be a source of craniofacial and cervical pain. The syndrome is characterized by a variety of symptoms including difficulty in swallowing, sore throat, glossodynia, headache and hemifacial pain. Sometimes, the pain is localized or radiates to the jaw and ear and may simulate pain of dental origin. Diagnosis is readily made by radiographic examination and palpating the tonsillar fossa. The only effective treatment is surgical shortening of the styloid process. Three patients, two women and a man, underwent surgery in our department for symptomatic elongation of the styloid process. The surgical procedures were conducted under general anaesthesia via a cervical approach in one patient and intraoral approach in two patients. All patients were completely relieved after styloid process resection and did not have any postoperative complications, except for cervical numbness in one case.

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)

Forty-three mothers who had requested regional anaesthesia for elective Caesarean section were allocated randomly to receive either extradural anaesthesia with pH-adjusted 2% lignocaine with 1/200,000 adrenaline, or incremental spinal anaesthesia using a 32-gauge catheter with 0.5% plain bupivacaine. Increments of lignocaine or bupivacaine were given with the aim of achieving a block from T4 to S5. The spinal catheter was quicker to place (median 3 min, range 1-45 min, compared with median 10 min, range 1.5-50 min) and spinal anaesthesia was quicker to establish (median 20 min, range 10-46 min compared with median 48 min, range 15-59 min) compared with the extradural technique. The maximum height of the spinal block was significantly higher (median T3-4, range T5-T3) than the extradural group (median T5, range T6-T3). The total dose of intrathecal 0.5% bupivacaine was unpredictable, with a mean dose of 2.7 ml and a range between 1.5 ml and 7.4 ml. Haemodynamic stability and the quality of the block were similar between the groups. There were two mild spinal-headaches in the spinal group. All the spinal catheters were removed intact.

In a prospective, randomised double blind study we recorded the rate of complications in dental anesthesia in more than 1500 patients using 4 commonly known anesthetic solutions. 228 of our patients (18.3%) noted headaches postoperatively. Furtheron we found syncopes, failures of anesthesia and nausea. Double vision was noticed once intraoperatively (Articain) and postoperatively (Lidocain). We found a high standard of security in dental local anaesthesia.

The past year has provided us with some interesting studies concerning pharmacology and anesthesia during the puerperium. I review the prevalence of various anesthetic techniques, as well as the use of different aspiration prophylaxis regimens. I also look at innovations in the administration of epidural and subarachnoid anesthetics, including use of the Sprotte needle to prevent postoperative headache. A small study shows that vitamin administration to premature neonates may prevent periventricular hemorrhage. Furthermore, predelivery injections of glucocortoid may protect against bronchopulmonary dysplasia. I also review painstaking studies that help to better understand thyroid stimulation and regulation during pregnancy. I hope this paper helps the busy obstetrician understand some of the highlights of this year's new literature on obstetric anesthesia and pharmacology.

Continuous epidural anesthesia (CEA) is generally accepted as a routine method of regional anesthesia while there has been only limited application of continuous spinal anesthesia (CSA), due mainly to a lack of adequate spinal catheters. With the introduction of a new, ultra-thin spinal catheter (32 G) inserted via a thin puncture needle, some of the complications reported after CSA can be eliminated. We studied CSA versus CEA in lower-extremity operations. METHODS. We evaluated 33 patients in a prospective, randomized study. All were comparable with respect to age, anesthetic risk (ASA II-III), and pre-existing diseases. The only exclusion criterium was the presence of a coagulation disturbance. The CSA group consisted of 17 patients (mean age 75.5 +/- 0.1 year); 26 G puncture needle and 32 G catheter were used. The CEA group consisted of 16 patients (mean age 73.8 +/- 11.0 years); an 18 G puncture needle and 22 G epidural catheter with a stylet were inserted with the loss-of-resistance technique. Both catheters were placed with the patient in a sitting position and left in place for 24 h in order to administer local anesthetics (LA) for postoperative analgesia as required. Hemodynamic parameters-mean arterial pressure (MAP) and heart rate (HR)-were compared in each group at 5-min intervals for 30 min after administration of local anesthetic and at 10-min intervals during the operation. Additionally, the ECG, pulse oximetry, respiratory rate, diuresis, and blood gases were monitored. After placement of the catheter, patients in the CSA group received 1.9 ml (+/- 0.2) bupivacaine HCl 0.5%. Patients in the CEA group received 12.6 ml (+/- 2.5) bupivacaine HCl 0.5%. For statistical evaluation of the data we used mean values, standard deviation (+/-), the Kruscal-Wallis procedure, and Student's t-test for unpaired data. P less than 0.05 was considered significant. RESULTS. The mAPs in the CSA group generally remained lower than those of the CEA group. However, over the course of the operation as well as after repeated injections, the difference between the two groups decreased. Only at 5 min after administration of the initial dose was a statistically significant difference in blood pressures between the two groups observed. A clinically relevant, rapid decrease in blood pressure due to relatively high doses of LA was seen in 1 case in each group. The first reinjection of LA after the initial dose was after 1.9 h in the CSA group (bupivacaine HCl 0.5% 1 +/- 0.3 ml) and after 1.8 h in the CEA group (bupivacaine HCl 0.5% 4.5 +/- 1 ml). The total dose of bupivacaine in the CSA group was 0.18 ml/kg per hour versus 0.8 ml/kg in the CEA group. No post-dural puncture headache was observed in the CSA group. DISCUSSION. The catheter designed for CSA is easy to use, although because of its small diameter a certain manual dexterity is required. In addition, CSA resulted in a more rapid onset of action and more pronounced sensorimotor blockade than did CEA. Hemodynamic alterations and side effects were comparably low in both groups.

In the few case reports of hearing loss following spinal anesthesia, complete recovery of the hearing impairment has always been described. In nine cases with hearing loss following not only spinal anesthesia but also myelography and dural puncture, the hearing of three patients did not recover or only partly returned. Two cases went to court for malpractice. Their suits could be dismissed because it appears likely that this rare complication arises only in persons with a wholly or partially unobliterated aquaeductus cochleae due to loss of perilymphatic fluid into the cerebrospinal space. Hearing loss was seen in eight of nine patients in lower frequencies around 30-40 dB. In six patients there was impairment on both sides. Recovery of normal hearing occurred in six of the nine patients. Transient hearing loss may occur more often than is generally assumed, and the symptom may remain unnoticed when a severe post-dural puncture syndrome with headache, dizziness, and nausea dominates the attention of the patient. Not all cases of hearing loss proved to be fully reversible, but the individual risk for this complication is not predictable. The use of fine-gauge needles may reduce the leakage of cerebrospinal fluid through the dural puncture and thus lower the incidence.
