Neuraxial analgesia is the gold standard method for pain relief in labor. Several techniques can optimize both the initiation and maintenance of neuraxial labor analgesia. Initiation techniques such as combined spinal-epidural or dural puncture epidural may offer some advantages over standard epidural insertion. The use of ultrasound to assist with landmarking and optimizing block placement improves neuraxial success, and is particularly useful in certain patient populations. Maintaining labor analgesia with a regimen that includes background programmed intermittent boluses with a patient-controlled epidural analgesia component affords the best combination of pain relief and avoidance of undesired effects. These techniques are most effective when dilute local anesthetics with lipophilic opioids are utilized.

Patient controlled epidural anlagesia is a commonly used method for postoperative pain management. The purpose of this study is to determine the optimal concentration of sufentanil for patient controlled epidural analgesia. Twenty eight patients who underwent elective gastrectomy were enrolled in this study. Patients were randomly assigned to one of two groups of 0.5 µg/mL (group S1) and 0.7 µg/mL (group S2). At 2 hours, 1 day, 2 days and 3 days after surgery, the patient's pain degree was checked by numerical rating scale (NRS) and the presence of side effects was assessed. In both groups, the NRS decreased linearly with time. The NRS of the two groups differed but the trend of decrease did not show significant difference. The overall incidence of side effects was 45.5% (group S1) and 58.8% (group S2), respectively. Patient controlled epidural analgesia using sufentanil was effective in controlling postoperative pain, which was found to decrease with time. When comparing the two concentrations used in this study, 0.5 µg/mL had a lower incidence of side effects than the concentration of 0.7 µg/mL, and the pain relief trends of the two concentrations were similar.

BACKGROUNDThe palpation method is widely used in clinical practice to identify the puncture site of combined spinal-epidural (CSE) blocks, but it is usually difficult to accurately locate the puncture site in obese parturients. Accurate identification of the puncture site is crucial for successful CSE block. The objective of this study was to evaluate the impact of ultrasound imaging on the success rate of CSE puncture in obese parturients.

METHODSSixty obese parturients with a body mass index ≥ 30 kg/m(2) who were scheduled for caesarean section were randomized into two equal-sized groups for location of the puncture site: an ultrasound group and a palpation group. The success rate of puncture at the first puncture site, the number of puncture attempts, duration of CSE procedure, time taken to determine the puncture site, and the depth of the epidural space were compared between groups. The frequencies of complications such as puncture site hemorrhage, neurological damage, and inadvertent dural puncture were also studied.

RESULTSThere were no differences in age, body weight, height, body mass index, or gestational age between the two groups. The success rate of puncture at the first puncture site was significantly higher in the ultrasound group than the palpation group (100.00% vs. 70.00%, P = 0.004). The number of puncture attempts was significantly lower in the ultrasound group than the palpation group (χ(2) = 6.708, P = 0.035). The time taken for determining the puncture site was (0.30 ± 0.12) minutes in the palpation group and (2.60 ± 0.61) minutes in the ultrasound group (P < 0.001). The duration of CSE procedure was (7.67 ± 1.52) minutes in the palpation group and (9.37 ± 1.35) minutes in the ultrasound group (P < 0.001). The depth of the epidural space was similar in both groups (P = 0.586). Puncture site hemorrhage was observed in 6 (20.00%) patients in the palpation group and 2 (6.67%) patients in the ultrasound group (P = 0.255).

CONCLUSIONSUltrasound imaging improves the rate of successful puncture at the first puncture site and decreases the number of puncture attempts. It facilitates CSE puncture in obese parturients.

BACKGROUND: Patient-controlled epidural analgesia (PCEA) is known to provide good postoperative analgesia in many types of surgery including laparoscopic surgery. However, no study has compared PCEA with patient-controlled intravascular analgesia (PCIA) in laparoscopic radical prostatectomy (LARP). In this study, the efficacy and side effects of PCEA and PCIA after LARP were compared. METHODS: Forty patients undergoing LARP were randomly divided into two groups: 1) a PCEA group, treated with 0.2% ropivacaine 3 ml and 0.1 mg morphine in the bolus; and 2) a PCIA group, treated with oxycodone 1 mg and nefopam 1 mg in the bolus. After the operation, a blinded observer assessed estimated blood loss (EBL), added a dose of rocuronium, performed transfusion, and added analgesics. The numeric rating scale (NRS), infused PCA dose, and side effects were assessed at 1, 6, 24, and 48 h. RESULTS: EBL, added rocuronium, and added analgesics in the PCEA group were less than those in the PCIA group. There were no significant differences in side-effects after the operation between the two groups. Patients were more satisfied with PCEA than with PCIA. The NRS and accumulated PCA count were lower in PCEA group. CONCLUSIONS: Combined thoracic epidural anesthesia could induce less blood loss during operations. PCEA showed better postoperative analgesia and greater patient satisfaction than PCIA. Thus, PCEA may be a more useful analgesic method than PICA after LARP.

These days, the epidural administration. of morphine is commonly used for postoperative pain re lief because even small amount of morphine (3mg) is enough to have an effect on specific opiates receptors of the spinal canal. We report a prospective double blind study of the efficacy of a single epidural dose of morphine on pain after spinal decompression. Postoperative pain was assessed by a linear analogue pain score and by the additional require ment for systemic analgesics. The results obtained are as follows:l. In spinal decompression, the adminitration of epidural morphine is easy, effective and safe because the epidural space has been already exposured during operation. 2. After operation the epidural route of morphine administration will give pain relief for up to 12 hours excellently. 3. When epidural morphine is given at the time of operations, the use of systemic analgesics is much reduced. 4. The side effects of epidural morphine are much reduced due to the small amount of morphine required. This simple procedure is recommended as an effective and safe method of reducing postoperative pain.

BACKGROUNDRopivacaine and levobupivacaine have been introduced into obstetric analgesic practice with the proposed advantages of causing less motor block and toxicity compared with bupivacaine. However, it is still controversial whether both anesthetics are associated with any clinical benefit relative to bupivacaine for labor analgesia. This study aimed to compare the analgesic efficacy, motor block and side effects of bupivacaine, ropivacaine and levobupivacaine at lower concentrations for patient-controlled epidural labor analgesia.

METHODSFour hundred and fifty nulliparous parturients were enrolled in this randomized clinical trial. A concentration of 0.05%, 0.075%, 0.1%, 0.125% or 0.15% of either bupivacaine (Group B), ropivacaine (Group R) or levobupivacaine (Group L) with sufentanil 0.5 microg/ml was epidurally administered by patient-controlled analgesia mode. Effective analgesia was defined as a visual analogue scale score was

RESULTSThere were no significant differences among groups in the numbers of effective analgesia, pain scores, hourly local anesthetic amount used, sensory and motor blockade, labor duration and mode of delivery, side effects and maternal satisfaction (P>0.05). The relative median potency was bupivacaine/ropivacaine: 0.828 (0.602-1.091), bupivacaine/levobupivacaine: 0.845 (0.617-1.12), ropivacaine/levobupivacaine: 1.021 (0.774-1.354), respectively. However, a significantly less number of effective analgesia and higher hourly local anesthetic use were observed in the concentration of 0.05% than those of >or=0.1% within each group (P<0.05).

CONCLUSIONSUsing patient-controlled epidural analgesia, lower concentrations of bupivacaine, ropivacaine and levobupivacaine with sufentanil produce similar analgesia and motor block and safety for labor analgesia. The analgesic efficacy mainly depends on the concentration rather than the type of anesthetics.

STUDY DESIGN: Retrospective study. OBJECTIVES: This study was conducted to evaluate the effects of using an epidural steroid sponge for postoperative pain control in lumbar discectomy. SUMMARY OF LITERATURE REVIEW: There are many methods to control postoperative pain after lumbar discectomy, including opioid analgesics, epidural catheters, and epidural steroid Gelfoam sponges. MATERIALS AND METHODS: A total of 72 patients who underwent surgery between March 2011 and February 2014 were enrolled. Their average age was 54 years (range, 24–82 years). In group A (35 patients), Gelfoam was inserted after being soaked with a solution of 2% lidocaine (400 mg/20 mL; 1 vial) and dexamethasone (5 mg/mL; 1 ampoule). In group B (37 patients), it was inserted after soaking with normal saline. Postoperative pain was assessed by visual analogue scale (VAS) scores. Pain above 5 points was controlled by a narcotic analgesic agent, and the duration and number of postoperative interventions, the period of time before walking after the operation, and the period until the date of discharge after surgery were assessed and compared. The Mann-Whitney U test was used as a nonparametric method. P-values less than 0.05 were considered to indicate statistical significance. RESULTS: In group A, 15 patients did not require analgesics on the day of surgery. In 20 patients, no analgesics were needed on postoperative day (POD) 1. In group B, 8 patients on the day of surgery and 13 patients on POD 1 did not require analgesics. In group A, 26 patients were able to walk on the day of surgery, and all patients were able to walk on POD 1. In group B, 19 patients was able to walk on the day of surgery and all patients were able to walk on POD 1. The mean number of hospital days before discharge was 6.3 in group A and 8.2 in group B. CONCLUSIONS: By continuously releasing low doses of steroids into the epidural space, this technique provided satisfactory results for postoperative pain control.

OBJECTIVETo investigate the efficacy and safety of tetracaine hydrochloride in patient-controlled epidural analgesia (PCEA) after pulmonary lobectomy.

METHODSForty-three patients scheduled for elective pulmonary lobectomy under general anesthesia were randomly allocated into either tetracaine group (22 patients) or ropivacaine group (21 patients). In the tetracaine group, 0.15% tetracaine was used for postoperative PCEA, while 0.3% ropivacaine was used in the ropivacaine group. The duration of postoperative analgesia was 48 h. The PCEA included a bolus of 6 ml with a lockout time of 1 h. Postoperative pain score was measured by visa analogue scale (VAS). Forced expired volume at the 1st second (FEV1.0), forced vital capacity (FVC), FEV1.0/FVC and peak expired flow (PEF) were measured preoperatively and daily after surgery. Hemodynamics were monitored and recorded before and after each administration of local anesthetics during the period of the study.

RESULTSVAS scores in both groups decreased significantly after a bolus injection of local anesthetics. There was no significant difference between the two groups in VAS either before or after the administration of PCEA. On the 1st and 2nd days after the operation, pulmonary function was reduced in both groups. However, there were no significant differences between the percentage of the changes of FEV1.0, FEV1.0/FVC and PEF in the two groups. There were also significant differences between the percentage of the changes of heart rate, mean arterial blood pressure and SpO2 after administration of local anesthetics. There was no significant difference in overall satisfaction with pain relief.

CONCLUSIONSThe analgesic effect of 0.15% tetracaine is similar to that of 0.3% ropivacaine used in patient-controlled epidural analgesia after thoracotomy. No serious side effects were observed.

OBJECTIVETo probe the effect of previous analgesia of scalp acupuncture.

METHODSSixty cases of radical operation of intestinal cancer were randomly divided into 2 groups: a scalp acupuncture plus epidural analgesia (scalp acupuncture group) and an epidural analgesia group, 30 cases in each group. The scalp acupuncture group received scalp acupuncture from 20 min before operation to the end of the operation, and epidural analgesia at the end of the operation. The epidural analgesia group only received epidural analgesia at the end of the operation. Recovery of VAS scores, BCS scores and gastrointestinal function after operation were investigated to probe into effects of scalp acupuncture on epidural morphine analgesia after operation in the patient of intestinal cancer.

RESULTSThe VAS scores at 6 h, 12 h, 24 h and 48 h in the scalp acupuncture group were lower than the epidural analgesia group, with significant differences at 6 h and 12 h between the two groups (P < 0.05). BCS scores at the 4 time points in the scalp acupuncture group were lower than the epidural analgesia group with significant differences between the two groups (all P < 0.05). The scalp acupuncture group in recovery of bowel sound, exsufflation from the anus in the scalp acupuncture group was faster than the epidural analgesia group (P < 0.01).

CONCLUSIONScalp acupuncture has a certain previous analgesic effect, reducing discomfort of the patient after operation and promoting the recovery of gastrointestinal functions.
