Aim: Aim of the study was to evaluate the effectiveness of micronized palmitoylethanolamide (PEA)-transpolydatin in the treatment of chronic pelvic pain in women affected by endometriosis., Methods: Twenty-four patients with suspected endometriosis affected by severe pelvic pain were enrolled. All patients received two tablets a day of PEA 400 mg and 40 mg polydatin for 90 days consecutively. A Visual Analogic Scale was used for the assessment of the severity of global pain, dysmenorrhea, dyspareunia, dysuria and dischezia. A second questionnaire was submitted to patients to assess the quality of life. The compilation of a diary lead us to evaluate the monthly assumption of any painkillers. Patients were evaluated at the begin of the treatment and then monthly until the end of the study (90 days). The statistical analysis was performed by using the ANOVA for the analysis of variance., Results: Statistically significant results were found in relation to pelvic pain, dysmenorrhea and dyspareunia compared to the initial evaluation of patients. Results related to dysuria and dischezia were not statistically significant (P>0.05). The decrease in pelvic pain leads to an improvement of the quality of life of patients. A decreased assumption of nonsteroidal anti-inflammatory drugs (NSAIDs) was also observed., Conclusion: PEA could be considered an effective supplement to conventional analgesic therapies in the management of pelvic pain related to endometriosis.

Aim: Infraclavicular brachial plexus block were first described by Raj, yet this block remained underutilized despite theoretical advantages. The aim of this prospective, randomized study was to compare equipotent doses of levobupivacaine and ropivacaine., Methods: For this prospective, randomized study we have enrolled, after informed consent, 30 patients of both sexes, ASA status I-II, who were going to receive surgery to the forearm or hand with tourniquet position on the arm. The infraclavicular plexus block was performed by using vertical technique. The block was performed with 30 mL of levobupivacaine 0.5% or ropivacaine 0.75%., Results: No differences were reported between 2 groups in terms of demographic data. The onset-time for motor block was greater for ropivacaine group (p<0.05); the sensitive block was longer in levobupivacaine group (p<0.05)., Conclusions: The long duration of sensory block associated with the with good analgesia, less toxicity and the pharmacodynamic properties of levobupivacaine include this new local anaesthetic as a valid choice respect other local anaesthetic for infraclavicular plexus block.

Aim: The aim of this study was to compare the clinical profiles of psoas block and sciatic nerve block performed with either 0.5% levobupivacaine or 0.75% ropivacaine., Methods: With ethical committee approval and written informed consent 80 ASA physical status I-II patients, undergoing lower extremity surgery received intravenous premedication with midazolam (0.05 mg/kg) and atropine (0.01 mg/kg). Patients were randomly allocated to receive a lumbar plexus block with: Levobupivacaine Group (L) 30 ml of 0.5% levobupivacaine or Ropivacaine Group (R) 0.75% ropivacaine, and sciatic nerve block with: Group R 10 ml 0.75 ropivacaine or Group L 0.5% levobupivacaine. The onset time and duration of nerve block were evaluated., Results: The motor onset time was shorter in Group L than in Group R. The motor offset time was similar in the 2 groups, the time being slightly greater for Group R. Group L presented a higher difference of resolution to motor-sensitive block compared to Group R., Conclusions: The differences between Groups L and R were characterised by: a faster motor onset time in Group L with a longer time between motor and sensitive resolution determining a lower demand for analgesic drugs postoperatively and greater support for motor control recovery.

Aim: In this study the authors compared the clinical profile of 2 local anesthetic drugs in the sciatic nerve block used during hallux valgus correction, a surgical procedure known to be post-operatively extremely painful. Since hallux valgus correction is painful post-operatively, many attempts have been tried to ensure a long-lasting analgesia. Block of the sciatic nerve appears to be the right choice balancing ease to performance, satisfaction of the patient and duration of action., Methods: The authors investigated the use of 20 ml of 0.5% bupivacaine or 0.75% ropivacaine regarding the speed of onset, quality and length of duration of sciatic nerve block performed with a lateral popliteal approach. Sixty ASA I-III patients (aged 19-73 years) were enrolled in this trial. Written informed consent was asked and obtained. A 20 G 50 mm Teflon coated Crawford needle, delivering 0.5 mA at 2 Hz, was used to locate and block the sciatic nerve in the popliteal fossa with a lateral approach., Results: Patients in the ropivacaine group required about 13 minutes to achieve a complete block and about 16 minutes were needed in the bupivacaine group for the anesthesia to be complete. The length of analgesia was 16 h for the ropivacaine group and 13 h for the bupivacaine group. This kind of approach to block the sciatic nerve appeared to the authors to be very easy to perform, with the patient lying in a natural position. Surgical anesthesia required less than 30 min in both groups to be ready, while the ropivacaine group had a longer length of analgesia compared to the bupivacaine group., Conclusions: Patient satisfaction was high in both groups.

Background: The aim of this study was the comparison of clinical profile of sciatic nerve block performed with either 0,5% levobupivacaine, 0,5% bupivacaine, or 0,5% ropivacaine., Methods: With ethical committee approval and written informed consent 45 ASA physical status I-II patients, undergoing elective hallux valgus repair received intravenous premedication with midazolam (0,05 mg/kg) followed by femoral nerve block with 15 ml of 2% mepivacaine. Then patients were randomly allocated to receive a sciatic nerve block with 20 ml of either 0,5% levobupivacaine (n=15), 0,5% bupivacaine (n=15), or 0,5% ropivacaine (n=15). An independent blind observer evaluated the onset time and duration of nerve block and postoperative analgesia. Postoperative analgesia consisted of 100 mg IV ketoprofen every 8 hours with the first administration at request., Results: The onset time of sciatic nerve block was 15 (5-60) min with levobupivacaine, 30 (5-60) min with bupivacaine, and 15 (5-60) min with ropivacaine (P = NS). No differences in the quality of nerve block as well as in the nerve block resolution times were observed among the three groups. The duration of postoperative analgesia was 16 (8-24) hours with levobupivacaine, 14 (8-24) hours with bupivacaine, and 17 (8-24) hours with ropivacaine (P=NS)., Conclusions: Using 0,5% levobupivacaine for sciatic nerve block results in similar clinical effects as those produced by using the same volume and concentration of either bupivacaine or ropivacaine.

Background: Pain, postoperative ileus, nausea, vomiting are the universal complications after major abdominal surgery. The aim of this study was to assess pain relief, side effects and recovery of gastrointestinal function during epidural analgesia with ropivacaine plus sufentanil and ropivacaine plus morphine after major abdominal surgery., Methods: In this prospective study, sixty patients (median age 62+/-12 years) undergoing major abdominal surgery, after informed consent, were randomized into two groups, during a period of 3 months. Patients who were not considered suitable candidates for epidural anaesthesia were excluded. Epidural catheters were inserted at T8-T9 (upper abdominal surgery) or T9-T11 (lower abdominal surgery) and ropivacaine 0,5% 7-9 ml (upper abdominal surgery) or 10-12 ml (lower abdominal surgery) combined with sufentanil 30 mcg (group S, n=30) or with morphine 2 mg (group M, n=30) was injected. General anaesthesia was induced and a continuous epidural infusion of ropivacaine 0.5% 5-10 ml/h was begun. Postoperatively, continuous epidural administration of ropivacaine 0.2% plus sufentanil 0.5 mcg/ml (group S) or ropivacaine 0.2 plus morphine 0.02 mg/ml (group M) was continued. Data on the quality of analgesia, recovery of gastrointestinal function and all side effects were recorded for 48 hours., Results: Incident and resting pain scores were not significantly different among group; although sufentanil provided better resting pain scores at 16th, 20th, 24th hours, and incident pain score at 24th hour. The incidence of nausea, vomiting and pruritus was more in morphine group (p<0,0001). Time to the first flatus was significantly shorter for patients in the sufentanil group (p<0,0001). The quality of pain relief assessed by the patients was rated as good in all patients., Conclusions: Continuous administration of epidural ropivacaine combined with sufentanil or with morphine resulted in good analgesia. Epidural analgesia with ropivacaine plus sufentanil provided the best balance of analgesia, side effects and recovery of gastrointestinal function.

We have compared the onset time, anesthetic potency and adverse effects of three local anaesthetics (ropivacaine, levobupivacaine and bupivacaine) in two type of peripheral blocks (brachial plexus block for upper limb and femoral nerve block for lower limb) in adult patients in a double blind, randomized, prospective study. A total of 66 patients undergoing orthopaedic surgery were randomly allocated to receive brachial plexus block or femoral nerve blockade with 0,5% ropivacaine (group R, n=22), 0,5% levobupivacaine (group L, n=22) or 0,5% bupivacaine (group B, n=22), each groups has been divided into two subgroups (LBP n=11, RBP n=11, BPB n=11, LBF n=11, RBF n=11, BBF n=11) dipending on the type of block. The onset of sensory nerve block was similar for the three groups; the onset of motor block and onset time ready to surgery were faster in group R (-30%) if compared with group L and B. The duration of motor block and sensory block was respectively longer in group L and in group B. Study results have not been influenced by the blocks, except for plexus nerve block where we observed the same results for group B and group R in relation to onset time ready to surgery. VRS scores were higher in group R as showed by the number of analgesic request in postoperative period. We did not observe any adverse effect. We conclude that ropivacaine acts faster with less interpatient variability, while levobupivacaine and bupivacaine offer a prolonged postoperative analgesia. For this reason, with the exception of bupivacaine due to major cardio and neuro toxicity, we can indifferently use levobupivacaine or ropivacaine depending on the requested characteristics of the anesthetic.

Objective: To evaluate the efficacy and security of the cervical plexus block and the continuous cervical peridural anaesthesia in carotid surgery, using ropivacaine as local anaesthetic., Methods: 90 patients (ASA II-III, age 67-84) who had signed informed consent were randomised in two groups. In Group C continuous cervical plexus block was performed using ropivacaine 0,75% 2,5 mg/kg. In Group P continuous cervical peridural anaesthesia was performed, at level C6-C7 or C7-T1, introducing the catheter for 5 cm into the epidural space and injecting in 20 min ropicavacine 0,5% 0,9 mg/kg together with 50-100 g of fentanyl. ECG, HR, arterial blood pressure, neurological status of conscious patient and eventual complications were all monitored., Results: Demographical data, duration of surgery and level of anaesthesia were all uniform in both groups. At the onset of the block the values of the systolic arterial blood pressure were significantly lower in Group P compared to Group C. One case of intradural injection of ropivacaine was reported and one case of intravascular injection, without remaining deficits. There were no perioperative complications., Conclusions: cervical plexus block and continuous cervical peridural anaesthesia performed with ropivacaine are both effective for anaesthesia in carotid surgery. Ropivacaine, for its minor cardiotoxicity, yields eventual complications related to the two methods, less severe.

This comparative study of low doses of ropivacaine was conducted in order to identify the most effective form of analgesia during labour with the aid of supplementary low doses of fentanyl and clonidine. 60 ASA I and II parturient primipares who had asked for epidural analgesia were randomly assigned to two groups. Group R was given 5-7 ml 0.2% ropivacaine and Group B 0.125% bupivacaine with both groups receiving 75 ng clonidine and 50 ng fentanyl with their first bolus of local anaesthetic. The parameters measured included the speed and spread of the sensory blockade and the scale of any motor blockade. The material haemodynamics and VAS pain relief scores were also measured at 30-minute intervals during labour and all side-effects (nausea, vomiting, localised or generalised itching, headache etc) were also monitored. Apgar anaesthetics and other drugs was decided on the basis of the VAS score (a further dose was given to women with a VAS of > 3-4). The study was completed by a telephone interview 6 months after delivery and the data were analysed using the Student's t-test and the chi 2 test. The analgesic effect was satisfactory in both groups and no statistically significant differences were found between the two groups under most of the headings analysed, apart from the top-up doses needed to maintain adequate analgesia. The average time between the first VAS to parturition was 292 mns in Group B and 267 mns in Groups R. Top-up doses of local anaesthetic (2.35 vs 5.05) came on average to 15.8 ml in Group B compared to 24.1 ml in Group R. There were 20% Caesarian sections in Group R and 13.8% in Group B. Optimum analgesia was achieved in Group R, the level of analgesia was insufficient or barely sufficient in 3.3% of cases. There was no Apgar score < 7 in either group. It was therefore concluded that both bupivacaine and ropivacaine offer excellent analgesia during labour and have no significant side effects on mothers or babies.

In the light of the recent addition of ropivacaine as a local anesthetic to our pharmacopeia, its effects at the cervical level are examined. A patient undergoing TEAC was given continuous epidural anesthesia with ropivacaine 0.5% (total dose: 167.5 mg in three hours) at C6-C7. No supplementary i.v. anesthetic was administered intraoperatively. The results obtained were compared with those of a similar case as to type of pathology and anesthetic technique, who was anesthetised with bupivacaine 0.375% (total dose: 112.5 mg in three hours-continuous epidural anesthesia) + fentanyl (0.18 mg), supplemented intravenously with ketoprophene (200 mg) + fentanyl (0.15 mg) for analgesic reasons. From this comparison, ropivacaine 0.5% was found to have greater anesthetic potential than bupivacaine 0.375%. However, it did not appear that ropivacaine exerted a protective effect on cardiovascular conditions in the course of carotid surgery. Further anesthesiologic experiences are needed to define the validity of ropivacaine in cervical surgery.
