Abstract
Pethidine (meperidine) is a unique member of the opioid family. In addition to its analgesic activity, it also has significant local anaesthetic activity. This property enables it to be used as the sole agent for spinal anaesthesia. We describe the successful use of intrathecal pethidine 1 mg/kg for an elective lower segment caesarean section in a patient presumed to be allergic to amide local anaesthetics. There were no significant adverse effects in either the mother or the newborn.

Abstract
The authors, using a crossover design, randomly administered, in a single-blind manner, inferior alveolar nerve blocks using 36 mg of lidocaine with 18 microg of epinephrine or a combination of 36 mg of lidocaine with 18 microg epinephrine plus 36 mg meperidine with 18 microg of epinephrine, at 2 separate appointments, to 52 subjects. An electric pulp tester was used to test for anesthesia, in 4-minute cycles for 60 minutes, of the molars, premolars, and central and lateral incisors. Anesthesia was considered successful when 2 consecutive 80 readings were obtained within 15 minutes and the 80 reading was continuously sustained for 60 minutes. Using the lidocaine solution, successful pulpal anesthesia ranged from 8 to 58% from the central incisor to the second molar. Using the lidocaine/meperidine solution, successful pulpal anesthesia ranged from 0 to 17%. There was a significant difference (P < .05) between the lidocaine and lidocaine/meperidine solutions for the lateral incisors through the second molars. We conclude that the addition of meperidine to a standard lidocaine solution does not increase the success of the inferior alveolar nerve block.

Abstract
The purpose of this prospective, randomized, single-blind study was to compare the anesthetic efficacy of lidocaine with epinephrine to lidocaine plus meperidine with epinephrine for inferior alveolar nerve blocks (IAN) in patients with mandibular posterior teeth experiencing irreversible pulpitis. Forty-eight emergency patients diagnosed with irreversible pulpitis of a mandibular posterior tooth randomly received, in a single-blind manner, 36 mg of lidocaine with 18 mug epinephrine or 36 mg of lidocaine with 18 mug of epinephrine plus 36 mg meperidine with 18 mug epinephrine, using a conventional inferior alveolar nerve block. Endodontic access was begun 15 minutes after solution deposition, and all patients were required to have profound lip numbness. Success was defined as no or mild pain (visual analog scale recordings) upon endodontic access or initial instrumentation. The success rate for the inferior alveolar nerve block using the lidocaine solution was 26%, and for the lidocaine/meperidine solution, the success rate was 12%. There was no significant difference (p = 0.28) between the two solutions. In conclusion, for mandibular posterior teeth with irreversible pulpitis, the addition of 36 mg of meperidine to a lidocaine solution administered in a conventional IAN block did not improve the success rate over a standard lidocaine solution.

Abstract
The authors administered intrathecal meperidine 10 mg to 10 healthy laboring women to determine its analgesic quality, onset, duration, and side-effect profile. When patients requested pain relief, we injected 10 mg preservative-free meperidine in 1 ml normal saline through a 32 gauge spinal catheter. We administered a second dose of meperidine 10 mg if analgesia was inadequate at 10 min. Additional doses of intrathecal meperidine or bupivacaine were administered on request. All patients received local anesthetic intrathecally or by infiltration for delivery. Eight patients were pain-free following meperidine 10 mg, the other 2 patients were comfortable after the second 10 mg meperidine dose. Three patients did not request further labor analgesics and delivered 58, 66 and 244 min following their initial injection of intrathecal meperidine. The mean duration of analgesia in the other 7 patients was 136 +/- 58 (mean +/-SD) min. Six of the 10 women in the study delivered vaginally; 3 spontaneously and 3 with vacuum or forceps assistance. Four patients delivered by cesarean section for failure to progress. Side-effects (which were easily treated) consisted of: pruritus (n = 1), vomiting (n = 2), hypotension (n = 2) and changes in fetal heart rate pattern (n = 5). All infants were vigorous and had good Apgar scores at birth. In conclusion, intrathecal meperidine is a promising labor analgesic, but the effect of meperidine on maternal blood pressure, fetal heart rate pattern, and the progress of labor need to be determined.

Abstract
The control of severe cancer pain may be problematic despite advances in pain management. Patients with severe intractable pain and/or intractable side effects may require aggressive interventional pain management strategies including the administration of medications by the continuous intrathecal route and/or neurosurgical procedures. Various medications, including opioids, local anesthetics, and alpha-2 agonists may be used intrathecally for the control of cancer pain. Failure of the intrathecal route may require the additional use of neurosurgical procedures such as cordotomy for pain control. We describe a case of severe cancer pain refractory to conventional intrathecal medications and cordotomy that was successfully managed by the addition of meperidine to the intrathecal regimen.

Abstract
Intraspinal pentazocine, 1.5 mg/kg, produced sufficient analgesia and moter block in 50 cases of abdominal total hysterectomy. Pentazocine, a derivative of benzomorphans, shares some common characteristics with local anesthetics in the chemical structure. Both agents have an aromatic ring and an intermediate chain, in common, which connects the former to nitrogen moiety, and the local anesthetic action was anticipated. The onset of the sensory block was 3.2 +/- 0.9 (mean +/- SD) min, and the maximum level was T10 and T4 with mean level of T6. The onset of motor weakness at the knee was 4.1 +/- 1.9 min, and the duration was 108 +/- 10.5 min.

Abstract
Spinal anaesthesia in the outpatient is characterized by rapid onset and offset, easy administration, minimal expense, and minimal side effects or complications. Spinal anaesthesia offers advantages for outpatient lower extremity, perineal, and many abdominal and gynaecological procedures. Development of small-gauge, pencil-point needles are responsible for the success of outpatient spinal anaesthesia with acceptable rates (0-2%) of postdural puncture headache (PDPH). Compared with peripheral nerve blocks, spinal anaesthesia has a more predictable offset. There are many possible choices of local anaesthetics for outpatient spinal anaesthesia. These include lidocaine, prilocaine, mepivacaine and small doses of bupivacaine. Meperidine has local anaesthetic properties in addition to its opiate properties. It has been used as the sole intrathecal agent for spinal anaesthesia but has no real advantages over lidocaine. Mepivacaine and lidocaine have each been associated with transient neurological symptoms (TNS) following intrathecal administration. This has stimulated development of alternative agents, including combinations of local anaesthetics and opioids. Lidocaine remains the most useful agent for outpatient spinal anaesthesia. For longer procedures, mepivacaine is an excellent spinal anaesthetic agent. Attention to technique, reduction of dose and addition of fentanyl to lidocaine result in effective spinal anaesthesia with rapid recovery and a low incidence of significant side effects or complications.

Abstract
Laparoscopic cholecystectomy is widely used and may be performed as an ambulatory procedure. We undertook a randomized comparison of the benefits of intraperitoneal pethidine compared with intramuscular pethidine for postoperative analgesia following laparoscopic cholecystectomy. A series of 100 consecutive American Society of Anesthesiologists (ASA) I or II patients were randomly assigned to intramuscular pethidine (54 patients) or intraperitoneal pethidine (46 patients). Each was combined with intraperitoneal bupivacaine. The primary endpoints were the pain and nausea scores at intervals after operation. All recruited patients completed the study. Pain scores at rest and upon movement were significantly lower in the group receiving the intraperitoneal pethidine at each of the time periods examined (pain at rest at 4 hours: 1.6 +/- 0.8 vs. 2.4 +/- 0.9 cm; p < 0.001; pain upon movement at 4 hours: 2.1 +/- 0.9 vs. 3.1 +/- 1.2 cm; p < 0.001). The total dose of pethidine administered via patient-controlled analgesia (PCA) during the first 24 hours after surgery was also significantly lower in this group (total dose 50.9 +/- 3.9 vs. 55.9 +/- 4.4 mg; p < 0.001). There were no significant differences in the respiratory rate at any of the time periods. Intraperitoneal pethidine analgesia was superior to an equivalent dose of intramuscular pethidine for the relief of postoperative pain in patients undergoing laparoscopic cholecystectomy. This was achieved at the expense of increased nausea but no significant increase in vomiting. The accessibility of this route of analgesia administration has implications for patients undergoing laparoscopic procedures, particularly with the recent trend toward increased use of ambulatory techniques.

Abstract
BACKGROUND The research on conductive analgesia induced by perineural opioids generated a large body of conflicting data. In this study we reassessed the antinociceptive response to perineural administration of morphine, fentanyl or meperidine in a rat model. METHODS Analgesia was assessed using the hind paw withdrawal latency (HPWL) response to radiant heat. The opioid dose producing 20% of maximal possible effect (20%MPE) for systemic analgesia was calculated for each drug. Then sciatic blockade was performed with the dose corresponding to 20%MPE. The injected hind paw was used to measure direct perineural effect and the contralateral hind paw was used as an indicator of systemic effect. RESULTS The response latency produced by morphine or fentanyl was not significantly different for ipsilateral (perineural effect) or contralateral (systemic effect) paw (27+/-11 vs. 28+/-16 and 3l+/-16 vs. 23+/-16 s, respectively). However, the meperidine group showed significantly higher %MPE for the ipsilateral paw (79+/-32 s) than for the contralateral paw (27+/-22 s). CONCLUSIONS The results indicate that perineural fentanyl or morphine do not produce analgesia. Perineural block produced by meperidine was attributed to local anesthetic-like effect, rather than to drug interaction with opioid receptor.

Abstract
UNLABELLED Patients undergoing laparoscopic procedures may experience postoperative pain. The intraperitoneal (IP) administration of drugs is controversial but has proven effective in some studies for the relief of postoperative pain. However, some investigators have not been able to confirm the analgesic efficacy of IP local anesthetics. The administration of IP opioids for the relief of postoperative pain has received little attention. At the end of laparoscopic tubal ligation, 100 patients received 80 mL of 0.125% bupivacaine with 1:200,000 epinephrine IP and 50 mg of meperidine either IP or IM. Postoperative pain scores were measured at rest and with movement. Pain scores were significantly lower in the group receiving the IP meperidine both at rest (P: < 0.01) and with movement (P: < 0.05). We conclude that the combination of intraperitoneal bupivacaine and intraperitoneal meperidine was better than the combination of IP bupivacaine and IM meperidine for postoperative analgesia in patients undergoing laparoscopic tubal ligation. IMPLICATIONS The combination of bupivacaine and meperidine delivered to the intraperitoneal cavity proved superior to equivalent doses of intraperitoneal bupivacaine and IM meperidine for postoperative pain relief in patients undergoing laparoscopic tubal ligation. Intraperitoneal delivery of analgesia proved effective in this study and merits further study and more widespread use.

Abstract
Spinal anesthesia can be used effectively and efficiently for a variety of cases in both the inpatient and the ambulatory surgery setting. Choice of agent, dose, distribution, use of adjuncts, and occasionally the use of continuous spinal anesthesia can tailor the spinal anesthetic to a specific type and duration of surgery. Although spinal anesthesia is extremely safe, adherence of new guidelines for patients receiving anticoagulant drugs, LMWH in particular, may minimize the risk of neurologic injury from spinal bleeding. At present, intrathecal adjuncts, such as neostigmine and clonidine used with local anesthetics, have shown limited usefulness, whereas lipophilic opioids, such as fentanyl, appear to increase duration and quality of spinal block without increasing the time to recovery. In the future, shorter-acting local anesthetics, possibly in conjunction with continuous catheter technologies, may reduce recovery times after spinal anesthesia without increasing risk. Spinal agents with long-acting analgesic properties that do not produce sensorimotor deficits may go beyond the immediate perioperative period and relieve postoperative pain. Currently there is controversy surrounding the use of spinal lidocaine and the occurrence of TNS, especially in the outpatient setting. The prudent use of small-dose bupivacaine and possibly procaine may reduce this risk, further supporting the use of spinal anesthesia for ambulatory as well as inpatient surgical procedures.

Abstract
PURPOSE Meperidine has local anesthetic properties and, therefore, when given epidurally it has the potential to cause hemodynamic changes. Our objective was to study the hemodynamic effects of an analgesic dose of epidural meperidine (50 mg) in 34 ASA 1-2 term parturients scheduled for elective Cesarean section under epidural anesthesia. METHODS A lumbar epidural catheter was inserted and patients lay in the supine left wedge position. Intravenous fluid preload was withheld, and hemodynamic measurements comprising of mean arterial pressure, cardiac output and heart rate were made using automatic oscillotonometry (Dinamap 1486SX) and transthoracic electrical bioimpedance (Bomed NCCOM3). Following baseline measurements, the hemodynamic effects of sequential epidural injection of first, 10 ml saline, and 20 min thereafter, 50 mg meperidine diluted to 10 ml with saline, were recorded. Sensory blockade was assessed following each injection using loss of temperature discrimination to ice. Paired Student t tests were used to compare changes in hemodynamic variables. RESULTS Epidural meperidine produced a small increase from the saline values in the mean (SD) cardiac output of 5.81 +/-1.44 to 6.04+/-1.54 L x min(-1) (P<0.05), and mean arterial pressure of 77.1+/-8.8 to 79.3+/-9.9 mm Hg (P<0.05). Sensory changes, the upper level of which ranged from L1 to T1, were detected in 94% of patients given epidural meperidine. Epidural saline injection had no such hemodynamic effects, but produced a detectable sensory level in two patients. CONCLUSION Epidural meperidine, 50 mg, caused minimal hemodynamic changes in term parturients.

Abstract
UNLABELLED The intrathecal injection of 0.7-1 mg/kg meperidine provides spinal anesthesia of only short duration. In this study, we investigated the effects of three different doses of meperidine for spinal anesthesia on the duration and level of sensory block and the incidence of side effects. Forty-five African men were randomly allocated to receive one of three doses of intrathecal meperidine: Group A = 1.2 mg/kg, Group B = 1.5 mg/kg, and Group C = 1.8 mg/kg. The duration of sensory block was significantly longer after 1.5 mg/kg compared with 1.2 mg/kg meperidine (112 +/- 19 vs 79 +/- 27 min; P = 0.001). Increasing the dose to 1.8 mg/kg did not further increase the duration of block. The level and the onset of the block were not affected by the dose. Common side effects were fatigue (27%), pruritus (20%), and nausea (7%). Seven patients had respiratory depression and seven had a decrease of systolic arterial blood pressure (SAP) >30% from baseline. There was no difference in the incidence of any side effect among groups. Respiratory depression and decreases in SAP were observed 5-50 min after meperidine injection. Twenty-two patients had no pain after the sensory block had terminated. We conclude that increasing the dose of meperidine from 1.2 to 1.5 mg/kg increased the duration, but not the level, of sensory block without an increase in side effects. IMPLICATIONS Intrathecal meperidine 1 mg/kg provides surgical anesthesia for only 40-90 min. We investigated the effects of three larger doses of meperidine in 45 African men. The 1.5 and 1.8 mg/kg doses provide a longer duration of anesthesia compared with 1.2 mg/kg. Nausea, pruritus, and respiratory depression were common in all dose groups. We conclude that increasing the dose of meperidine from 1.2 to 1.5 mg/kg increased the duration, but not the level, of sensory block without an increase in side effects.

Abstract
Two groups of 40 homogeneous patients (ASA physical status (1-2)) with idiopathic scoliosis undergoing spinal fusion with CD instrumentation were studied prospectively. Group A (intrathecal) received a mixture of morphine and sufentanil administered intrathecally at the level of L3-L4 after the induction of anaesthesia. Group B (control) had inhalation and intravenous narcotic anaesthesia. The use of intrathecal opioids resulted in a significant reduction of blood pressure without the use of any hypotensive agents and produced prolonged postoperative analgesia. There was no adverse effect on somatosensory evoked potentials. The dose requirement for the anaesthetic agents was significantly reduced and the blood loss was 27% of their blood volume compared with 53% in the control group. No long or short term impairment of cerebral or spinal function was observed. The use of intrathecal opioids supplemented with other anaesthetic agents is an alternative method with multiple benefits for any major surgery such as spinal fusion.

Abstract
Pethidine is the only member of the opioid family that has clinically important local anaesthetic activity in the dose range normally used for analgesia. Pethidine is unique as the only opioid in current use that is effective as the sole agent for spinal anaesthesia. In lower doses, intrathecal pethidine is also an effective analgesic for treating pain in labour. This paper reviews the pharmacology of intrathecal pethidine and clinical experience reported to date. Articles reviewed include those identified by a Medline search using keywords "intrathecal" or "spinal anaesthesia/ anesthesia" and "pethidine" or "meperidine". Reference lists from identified papers were scrutinized to identify further relevant articles.

Abstract

Immediately after venous occlusion with a tourniquet, I.V. fentanyl 150 microg (Group A, n = 35), morphine 4 mg (Group B, n = 35), meperidine 40 mg (Group C, n = 35), 2% lidocaine 3 mL (Group D, n = 35), or normal saline 3 mL (Group E, n = 35; as placebo control) was given to adult patients. The venous retention of the drug was maintained for 1 min, followed by tourniquet release and I.V. administration of propofol 100 mg. Pain assessment was made immediately after the propofol injection. Lidocaine and meperidine significantly reduced propofol injection pain more than placebo (P < 0.05), but there were more side effects in the meperidine group. Fentanyl and morphine reduced the intensity of propofol injection pain (P < 0.05) and had some effect in reducing the incidence of propofol injection pain, but the difference did not reach statistical significance. The order of efficacy was lidocaine approximately meperidine > morphine approximately fentanyl. We postulate that the peripheral analgesic effect of these opioid is due to their local anesthetic activity. IMPLICATIONS Propofol, a commonly used anesthetic, often causes pain on injection. Given as venous retention pretreatments 1 min before propofol, meperidine and lidocaine were found to significantly reduce the propofol injection pain, whereas fentanyl and morphine only slightly reduced the propofol injection pain.

Abstract
We aimed to determine the usefulness of intrathecal pethidine as the sole anaesthetic for transurethral resection of prostate (TURP) while comparing the incidence of hypotension with intrathecal bupivacaine. A double-binded randomized prospective trial was conducted involving 40 patients for TURP. The patients were divided equally into two groups; group A received 2 ml 0.5% bupivacaine intrathecally and group B received 40 mg pethidine intrathecally. Changes in blood pressure and heart rate were measured over the first 30 minutes. The highest sensory block and the time to reach it were documented. The degree of motor blockade was also recorded. There was no significant difference in the incidence of hypotension. The pethidine group had significantly greater reduction in heart rate, a lower degree of motor block, shorter period before requests for postoperative analgesia but a higher incidence of sedation, nausea and vomiting. Intrathecal pethidine did not offer any advantage over intrathecal bupivacaine for TURP.

Abstract
OBJECTIVE To report a continuous infusion of intrathecal meperidine via an implanted infusion pump for nonmalignant, chronic pain. CASE SUMMARY A 69-year-old white woman had chronic, nonmalignant low-back pain and bilateral leg pain. Multiple drug therapies and other interventional techniques had failed. The patient achieved significant pain relief by a continuous infusion of intrathecal meperidine via an implanted infusion pump. DISCUSSION To our knowledge, this is the first report of meperidine administered intrathecally by continuous infusion. Continuous infusion of intrathecal and epidural opiates by implanted infusion pumps is becoming more widely recognized as an alternative treatment for patients with chronic, benign pain. Epidural and intrathecal meperidine is an effective analgesic for short-term surgical procedures. Data reporting effective relief and safety with continuous intrathecal meperidine remain limited. CONCLUSIONS Continuous intrathecal meperidine via an implantable infusion pump may be an effective alternative in the treatment of chronic pain.

Abstract
Early first-stage labor pain is primarily visceral in origin. Increasing pain intensity and transition to somatic nociceptive input characterizes late first- and second-stage labor pain. The effect of this change in nociceptive input on the duration of intrathecal labor analgesia has not been well studied. This prospective cohort observational study compares the duration of intrathecal labor analgesia after intrathecal injections made in early labor (3- to 5-cm cervical dilation) and those made in more advanced labor (7- to 10-cm cervical dilation). Forty-one parturients (18 in early labor and 23 in advanced labor) received intrathecal sufentanil (10 micrograms) and bupivacaine (2.5 mg) as part of a combined spinal-epidural technique. Patients rated their pain using a 0-10 verbal pain scale prior to intrathecal injection and every 20 min thereafter. Duration of analgesia was defined as the lesser of time until the pain score exceeded 5 or until a request for supplemental epidural analgesia was made. The duration of spinal analgesia was significantly less when intrathecal injection was made in advanced labor (120 +/- 26 min) compared with early labor (163 +/- 57 min, P < 0.01). We conclude that cervical dilation and stage of labor significantly impact the effective duration of intrathecal sufentanil/ bupivacaine labor analgesia.

Abstract
Sixty patients took part in a randomised, double-blind study to compare the analgesic and side effects of three opioid-containing solutions for patient-controlled epidural analgesia following abdominal surgery. Patients in group 1 received a solution containing bupivacaine 0.125% with fentanyl 10 micrograms.ml-1, group 2 bupivacaine 0.125% with diamorphine 125 micrograms.ml-1, group 3 pethidine 2.5 mg.ml-1. All groups received 4 ml.h-1 background infusion and 3 ml boluses every 20 min if necessary. There were no significant differences between the groups in visual analogue scale pain scores (p = 0.537) or volumes of solution used at 24 h (p = 0.351) or 48 h (p = 0.105). Motor block was significantly higher in group 2 (p < 0.004) and pruritus occurred significantly less in group 3 (p < 0.05). We conclude that these three solutions produce equivalent analgesia but that pethidine 2.5 mg.ml-1 may be associated with fewer side effects.

Abstract
STUDY DESIGN Intraoperative recording of somatosensory-evoked potentials is useful for monitoring spinal cord tolerance during spinal fusion with instrumentation. Volatile anesthetic agents are known to have prominent suppressive effects on somatosensory-evoked potentials. This study evaluates the effect of intrathecal administration of opioid, consisting of morphine sulfate and sufentanil, on somatosensory-evoked potential monitoring. OBJECTIVES To study the effect of different anesthesia techniques on somatosensory-evoked potentials during spinal fusion. SUMMARY OF BACKGROUND DATA The effect of intravenous narcotic administration on somatosensory-evoked potentials has been well studied and reported. This study shows the effect of intrathecal opioids on somatosensory-evoked potentials. METHODS Ten patients scheduled for spinal fusion with Cotrel-Dubousset instrumentation were induced with thiopental and maintained with intrathecal morphine sulfate (20 micrograms/kg) and sufentanil 50 micrograms, supplemented with isoflurane 0.5% air and oxygen. Routine monitoring was done, including arterial line and continuous somatosensory-evoked potentials. Anesthesia was maintained constant, with a mean blood pressure of 55 mm Hg. Normocarbia and normothermia were maintained. Baseline somatosensory-evoked potentials were recorded using bilateral posterior tibial nerve stimulation, with constant somatosensory-evoked potential monitoring after the induction of anesthesia. RESULTS There were no significant changes in either latencies or amplitudes in cortical somatosensory-evoked potentials after opioid injection at any time during the surgical procedures. CONCLUSIONS Somatosensory-evoked potential monitoring was possible in all patients undergoing extensive spinal surgery. Intrathecal opioid anesthesia with low concentrations of isoflurane in air and oxygen seems to have no effects on somatosensory-evoked potentials.

Abstract
One hundred and fifty ASA 1 and 2 patients were randomly allocated to receive pethidine 25 mg (1 ml), lignocaine 10 mg (1 ml) or 0.9% saline (1 ml) on a double-blind basis, as pretreatment to reduce pain on injection of propofol. Both active treatments were significantly better than placebo at preventing pain (p < 0.01). Lignocaine was most effective in preventing pain in men (p < 0.05) whilst pethidine was more effective in women (p < 0.05).

Abstract
STUDY OBJECTIVE To determine the effect of intrathecal fentanyl on maternal hemodynamics. DESIGN Prospective. SETTING Labor and delivery suite of a university medical center. PATIENTS 23 ASA status I nonlaboring term parturients presenting for elective cesarean section. INTERVENTIONS Patients were given either 1,200 ml lactated Ringer's Solution (Group 1, n = 12) or no intravenous (i.v.) fluid (Group 2, n = 11). A combined spinal-epidural technique was then performed. Fentanyl 25 micrograms was administered intrathecally through a 24-gauge Sprotte or 25-gauge Whitacre spinal needle. After completion of the hemodynamic study, a catheter was threaded into the epidural space for local anesthetic administration. MEASUREMENTS AND MAIN RESULTS Baseline hemodynamic data [systolic (SBP), diastolic, and mean arterial pressure, heart rate, stroke volume, cardiac output, end-diastolic volume, and ejection fraction] were obtained in triplicate using noninvasive blood pressure monitoring and impedance cardiography. After administration of intrathecal fentanyl, hemodynamic measurements were recorded at 3-minute intervals for 30 minutes. These values were compared with baseline for both groups. Ten patients in each group completed the study. Intrathecal fentanyl administration did not result in any maternal hemodynamic changes in Group 1, and a few small statistically significant changes in Group 2. Measured SBP was always greater than 100 mmHg in all patients during the study. CONCLUSION Intrathecal administration of fentanyl 25 micrograms in nonlaboring term parturients does not produce clinically important maternal hemodynamic changes.

Abstract
PURPOSE To study the haemodynamic effects of intrathecal meperidine, administered either alone or mixed with bupivacaine. METHODS We studied 42 Chinese patients, aged 59-87 yr, scheduled for transurethral bladder or prostate surgery, randomized into three equals groups, that received either meperidine 0.8 mg.kg-1, meperidine 0.4 mg.kg-1 plus 1.5 ml of 0.5% heavy bupivacaine or 3 ml of heavy bupivacaine 0.5%. Non-invasive systolic (SAP) and mean (MAP) arterial pressures, central venous pressure and cardiac index, stroke index and heart rate (HR) measured by the BoMed NCCOM3-R7S bioimpedance device, were recorded over the first 25 min. Systemic vascular resistance index (SVRI) was derived. Onset of sensory and motor block was also measured. Decreases in MAP of 25% were treated with colloid and metaraminol. RESULTS The onset of block was slower in the meperidine group (P < 0.05). Decreases in SAP, MAP and SVRI (all; P < 0.001) occurred within five minutes in all three groups. The HR was increased in the bupivacaine group (P = 0.03), but bradycardias treated with atropine occurred in six patients receiving meperidine and four patients receiving the mixture. Six patients receiving meperidine and two patients receiving the mixture required general anaesthesia for inadequate block. The incidence of nausea and vomiting was higher in the patients receiving meperidine (P < 0.05). No other complications were encountered. CONCLUSIONS Intrathecal meperidine used alone or mixed with bupivacaine has no intra-operative advantage over heavy bupivacaine 0.5%.

Abstract
Anaesthesia, postoperative analgesia and the incidence of adverse effects after intrathecal pethidine hydrochloride 0.50 mg.kg-1 and 0.75 mg.kg-1 were assessed and compared with a conventional technique using isobaric bupivacaine 13.75 mg in patients undergoing transurethral resection of the prostate gland. Sensory and motor block were significantly shorter with both pethidine regimens than with bupivacaine (p < 0.001). Although sensory and motor block were shorter after pethidine 0.50 mg.kg-1 than after pethidine 0.75 mg.kg-1 the difference in duration was clinically insignificant. The incidence of incomplete motor block was significantly greater with pethidine 0.50 mg.kg-1 than with bupivacaine 13.75 mg.kg-1 (p < 0.01). Visual analogue pain scores recorded after the operation were low and were similar in the pethidine groups to those obtained with bupivacaine alone. Mean arterial blood pressure was significantly lower in both pethidine groups compared with the bupivacaine group between 30 and 240 min after intrathecal injection (p < 0.001). However, the within-group reductions in blood pressure were within clinically acceptable limits. The incidences of nausea and emesis were low and emesis occurred in patients in the bupivacaine group only (p < 0.03). Pruritus was seen only in patients receiving pethidine. Intra-operative sedation occurred more often in patients receiving both pethidine 0.50 mg.kg-1 and 0.75 mg.kg-1 compared with patients receiving bupivacaine (p < 0.04). Both pethidine regimens provided acceptable anaesthesia and there were no significant differences between the two regimens in quality of intra-operative anaesthesia, incidence of adverse events or postoperative analgesia.

Abstract
Intrathecal meperidine administration can provide surgical anaesthesia and postoperative analgesia for about two to six hours. We have observed two cases of respiratory depression associated with meperidine spinal anaesthesia. An 81-yr-old woman received 50 mg intrathecal meperidine for inguinal hernia repair. Supplemental oxygen was administered at 3 L.min-1 by nasal prongs. About 40 min later, the patient's oxygen saturation decreased from 97% to 87% and she was asked to take big breaths. She responded immediately and oxygen saturation returned to 97%. Two more similar episodes followed in the next five minutes. Naloxone 0.1 mg iv was administered and the oxygen saturation remained at 96-97% until completion of surgery about 15 min later. She had an uneventful recovery. A 24-yr-old healthy woman presented for tubal ligation eight hours after vaginal delivery of an infant. The surgical procedure was performed under spinal anaesthesia produced by 50 mg meperidine. During surgery, midazolam 2 mg iv was given for anxiolysis. About five minutes after admission to the postanaesthesia care unit, the patient's respiratory rate decreased to ten breaths per minute and oxygen saturation decreased to 89%. Supplemental oxygen at 3 L.min-1 was administered by nasal prongs. The patient was encouraged to take big breaths and the arterial oxygen saturation rapidly increased to 98-99%. Forty minutes later, nasal oxygen was discontinued. The patient maintained her oxygen saturation while breathing room air. She was then discharged to the ward and had an uneventful recovery course. We recommend that a patient's respiratory variables and oxygenation be closely monitored for at least one hour after intrathecal meperidine administration.

Abstract
In a double-blind, randomised study, we have examined the effects of the addition of pethidine 100 mg to 40 ml prilocaine 0.25% for intravenous regional anaesthesia in healthy volunteers. During intravenous regional anaesthesia the hand and forearm are isolated from the rest of the circulation and pethidine interaction with central opiate receptors does not occur. Pethidine increased the speed of onset and extent of sensory and motor block, reduced tourniquet and forearm pain, and subjectively improved the quality of the block. Pethidine has local anaesthetic action on peripheral nerves in vivo.

Abstract
The aim of this study was to determine whether the addition of a small dose of prilocaine could augment the spinal block induced by meperidine and affect intrathecal meperidine pharmacokinetic behaviour. Spinal anaesthesia was performed in 60 men scheduled for endoscopic resection of a prostatic adenoma or bladder tumour under spinal anaesthesia. They were allocated randomly to receive either 1 mg.kg-1 meperidine (Group 1, n = 30), or 1 mg.kg-1 meperidine plus 0.5 mg.kg-1 prilocaine (Group 2, n = 30). Blood samples were collected prior to and for 24 hr after spinal injection in 24 patients (12 in each group). Plasma meperidine levels were assayed by gas chromatography. Complete motor block was achieved in all Group 2 patients, but was incomplete in seven of Group 1 (P less than 0.05). The onset of both motor and sensory blocks was shorter (P less than 0.01) in Group 2 and the duration was longer (P less than 0.05). Coadministration of prilocaine modifies meperidine pharmacokinetic behaviour. The area under curve was 48% greater (P less than 0.01) and Cmax was higher in Group 2 than in Group 1, 145.8 +/- 42.2 vs 107 +/- 20.5 ng.ml-1 (P less than 0.001). No evidence of respiratory depression was noted in any of the patients. Despite the increase in plasma meperidine concentrations, no side effects were observed. The plasma concentrations remained at one third to one sixth the levels reported to induce a respiratory depression. It is concluded that the addition of prilocaine to meperidine improves motor and sensory block during surgery and alters meperidine kinetics without producing major side effects.

Abstract
Twenty-one patients were included in a randomized study to receive either 10 mg of 0.5% hyperbaric bupivacaine alone or combined with 0.05, 0.1, 0.2, 0.3, 0.4 or 0.5 mg.kg-1 meperidine for spinal anaesthesia. Sensory blockade was assessed by pin prick, motor blockade by the Bromage scale, and postoperative analgesia by VAS scores and by the time before the first demand for analgesia. Spinal meperidine did not change the duration of sensory blockade, but induced a dose-related increase in postoperative efficient analgesia. Spinal meperidine might be considered as a means to obtain postoperative analgesia in the hours immediately following surgery.

Abstract
The analgesic and adverse effects of intrathecal methadone 5 mg, 10 mg and 20 mg were assessed and compared with intrathecal morphine 0.5 mg. The study was conducted on 38 patients who underwent total knee or hip replacement surgery. The intrathecal opioid was administered at the end of surgery and assessments began 1 h thereafter and continued for 24 h. Pain measurements, supplementary analgesia requirements, and adverse effects were recorded. Intrathecal morphine 0.5 mg provided effective and prolonged analgesia. Intrathecal methadone 5 mg, 10 mg, and 20 mg produced good analgesia of 4 h duration. Thereafter the median pain scores with intrathecal methadone were consistently higher (worse) than those with intrathecal morphine (P less than 0.05). The time to the onset of discomfort severe enough to require supplemental morphine was longer after intrathecal morphine than following methadone (15 h with morphine 0.5 mg; 6.25 h, 6.5 h and 6 h with methadone 5 mg, 10 mg, and 20 mg respectively: P less than 0.05). Central nervous system depression manifesting as respiratory depression, hypotension, and excessive drowsiness occurred in 3 of 8 patients injected with methadone 20 mg intrathecally. Generalized pruritus, nausea, vomiting, and urinary retention were common and equally distributed among the treatment groups. We conclude that both intrathecal morphine 0.5 mg and methadone 5, 10, and 20 mg provide excellent analgesia but that morphine has a more prolonged effect. Methadone 20 mg produced unacceptable side effects. Clinical evidence for rostral spread of methadone within the CSF, as indicated by facial itching and excessive drowsiness, was less apparent with 5 mg than with 10 and 20 mg. Various explanations for the observed differences between the drugs are discussed.

Abstract
The purpose of this study was to determine if a small dose of intrathecal meperidine would achieve adequate spinal anaesthesia while minimizing complications and to compare its effectiveness with lidocaine. The spinal anaesthetic effects of five per cent lidocaine 0.5 mg.kg-1 in 7.5 percent glucose (n = 20) or five per cent meperidine 0.5 mg.kg-1 (n = 22) were evaluated in 42 ASA physical status II or III patients. Intrathecal injection of the anaesthetic agent was given with the patient in the sitting position in which he remained for ten minutes before being placed in the lithotomy position. The onset time for sensory blockade was seven minutes in the lidocaine group and ten minutes in the meperidine group. Final sensory levels were identical in both groups. Mean arterial blood pressure decreased significantly in the lidocaine group but not in the meperidine group. Motor block was absent in ten patients in the meperidine group but was present in all the patients in the lidocaine group. Duration of postoperative analgesia was 968 min in the meperidine group and 681 min in the lidocaine group (NS). Complications such as nausea, vomiting, itching, drowsiness and respiratory depression were similar in the two groups. It is concluded that low-dose meperidine, 0.5 mg.kg-1, is effective as a spinal anaesthetic agent and has few complications.

Abstract
Eleven male patients undergoing endoscopic resection for prostatic adenoma and bladder tumours under spinal anaesthesia received intrathecal pethidine 1 mg X kg-1. Plasma concentration and its evolution with time were assessed; pethidine plasma concentrations were determined by high performance liquid chromatography. Pethidine was rapidly and extensively absorbed. The peak plasma concentration of pethidine was 176 +/- 66 ng X ml-1 (range: 84-208) and the time to peak concentration was 2.3 +/- 1.4 h (range: 0.5-6 h). The terminal elimination half-life was 7.2 +/- 2.2 h (range: 4-11.5 h). The plasma concentrations of pethidine remained below 500-700 ng X ml-1, the minimum concentration necessary to obtain a systemic analgesic effect. Two patients required noramidopyrine as a complement at the 8th and 12th h respectively. No respiratory depression was observed. Intrathecal pethidine (1 mg X kg-1) was an effective agent for spinal anaesthesia: the prolonged postoperative analgesia was due to the drug acting on opioid receptors in the spinal cord. This led to the necessity of postoperative monitoring during 24 h after intrathecal pethidine administration.
