RESUMO
The aim of this study was to investigate the efficacy of peritubular infiltration and ultrasound-guided low thoracal paravertebral block in patients undergoing percutaneous nephrolithotomy (PCNL). Sixty patients, American Society of Anesthesiologists I-II, between the ages of 18 and 65 years undergoing PCNL were randomized into three groups. Group peritubal infiltration (Pi, n = 20) received infiltration along the nephrostomy tube 20 ml 0.25% bupivacaine, in 6 and 12 o'clock position. Group paravertebral block (Pv, n = 20) received single-shot paravertebral block with 20 ml 0.25% bupivacaine at the level of T8-T9. Group control (C, n = 20): no intervention is performed. Postoperative opioid consumption and pain scores, opioid-related side effects, and additional analgesic requirement were recorded. The fentanyl consumption in Group Pv was significantly lower in comparison to Group C in all time intervals (p < 0.05). In the comparison of Group Pv and Group Pi, fentanyl consumptions in the postoperative 0-4th hours (100.00 ± 50.65 and 145.00 ± 61.55, respectively), 4-8th hours (50.00 ± 64.88 and 121.25 ± 56.93 respectively), and in the total of 24 h (197.50 ± 133.74 and 368.75 ± 116.66 respectively) were significantly lower in Group Pv (p < 0.05). The dynamic VAS scores analyzed at the 1st and 2nd hours were significantly lower in Group Pv than Group Pi (p < 0.05). Eight patients in Group C, two patients in Group Pi and 1 patient in Group Pv required additional analgesics and the difference was significant (p < 0.05). Paravertebral block achieved more effective analgesia by reducing postoperative opioid consumption and VAS scores comparison to the control and peritubal infiltration groups in patients undergoing percutaneous nephrolithotomy.

INTRODUCTION: Low back pain (LBP) is a common complaint originating from muscles Myofascial pain syndrome (MPS) is mainly associated with trigger points (TrP) in the muscle tissue. We compared the intravenously administered non-steroidal anti-inflammatory drug (NSAID) and trigger point injection (TPI) in the treatment of LBP patients admitted to the emergency department due to pain caused by TrPs. MATERIAL AND METHOD: After randomization, NSAID was administered intravenously in group 1 and TPIs were performed as specified by Travell and Simons in group 2. The TrPs were identified with the anamnesis and physical examination Demographic characteristics and vital signs of the patients were recorded. Pain scores were measured with the Visual Analogue Scale (VAS) at admission; and in minutes 5, 10, 15, 30, and 60. RESULTS: There were 32 patients in group 1 and 22 patients in group 2. The demographics, vital signs, and pain scores at admission were not statistically significantly different between the groups. The pain scores decreased significantly in the TPI group. During the 60â¯min' follow-up period, the mean VAS pain score decreased by 0.41⯱â¯1.30 in the TPI group and by 2.59⯱â¯2.37 in the NSAID group (pâ¯<â¯0.001). Respond the treatment was significantly higher group TPI than Group NSAID (21/22 vs 20/32 respectively, pâ¯=â¯0.008). CONCLUSION: In this small randomized study with several methodological limitations, TPI was superior to the intravenous NSAIDs in the treatment of acute LBP due to TrPs. TPI can be used in the emergency departments for the acute treatment of LBP in selected patients.

BACKGROUND: Myofascial pain syndrome is defined as ``pain and/or autonomic phenomena referred from active myofascial trigger points''. Trigger point injection is an effective treatment option, which is widely used to treat myofascial pain. Trigger point injection in the cervicothoracic regions can be associated with pneumothorax. CASE: In this paper, we presented a patient who developed pneumothorax after trigger point injection. RESULT: This case report indicates there is a risk of pneumothorax during trigger point injection in the cervicothoracic regions.

PURPOSE: The effect of a single-dose of pre-emptive pregabalin is still unknown, although it is used as an adjuvant in controlling acute postoperative pain. The purpose of this study was to evaluate the effects of pre-emptive single-dose pregabalin on postoperative acute pain and 24-hour opioid consumption in patients who underwent double-jaw surgery. PATIENTS AND METHODS: Forty patients (18 to 45 yr old; American Society of Anesthesiologists status I to II) for whom elective double-jaw surgery was planned under general anesthesia were included in this study, which had been planned as a prospective, randomized, and double-blinded study. Patients were randomly divided into 2 groups: the pregabalin group (n = 20) was given pregabalin 150 mg orally 1 hour before general anesthesia and the placebo group (n = 20) was given an oral placebo capsule. The groups were administered the routine general anesthesia protocol. Postoperative analgesia was performed intravenously in the 2 groups twice a day with dexketoprofen trometamol 50 mg and patient-controlled analgesia with fentanyl. Postoperative analgesia was evaluated using the visual analog scale (VAS). Fentanyl consumption, additional analgesia requirement, and side-effects were recorded during the first 24 hours after surgery. Descriptive and bivariate statistics were computed, and significance was set at a P value less than .05. RESULTS: Compared with placebo, the VAS score was statistically lower in the pregabalin group during the early postoperative period (P < .05). The 24-hour opioid consumption was significantly higher in the placebo group compared with the pregabalin group (509.40 ± 261.56 vs. 260.10 ± 246.53 µq, respectively; P = .004). In addition, the analgesia requirement was statistically lower in the pregabalin group (P < .05). Nausea or vomiting was observed more often in the placebo group, whereas other side-effects were similar for the 2 groups. CONCLUSION: A single 150-mg dose of pre-emptive pregabalin decreased postoperative opioid consumption in the first 24 hours after double-jaw surgery. Multimodal analgesia techniques that contain pre-emptive analgesia can be used successfully in preventing postoperative pain caused by orthognathic surgery.

BACKGROUND: This study investigated the effects of metamizole and paracetamol on pain and oxidative stress induced by scalpel incision and carrageenan in rats. MATERIALS AND METHODS: Total of 144 rats were divided into groups of 12 animals. Six groups each were used for scalpel incision and carrageenan tests. Pain was inflicted by applying a scalpel incision or carrageenan. Pain-created groups by scalpel incision received metamizole (SIM) or paracetamol (SIP) at doses of 250 or 500 mg/kg. Pain-created groups by carrageenan received metamizole (CAM) or paracetamol (CAP) at doses of 250 or 500 mg/kg. Analgesic activity was determined by Basile Algesimeter. The COX-2 and MPO gene expressions were determined, and malondialdehyde and tGSH were measured in rat paws. RESULTS: In the scalpel incision test, pain was reduced in groups of SIM-250 and SIM-500 in the first hour by 65.2% and 91.3%, respectively, and in the third hour by 51.9% and 77.8%, respectively, compared with the SIC group. In SIP-250 and SIP-500 groups, pain was reduced in the first hour by 43% and 74%, respectively, and by 33.4% and 59.3%, respectively, in the third hour compared with the SIC group. In the carrageenan test, in groups CAM-250 and CAM-500, pain was reduced in the first hour by 72.3% and 86.1%, respectively, and by 65.8% and 71.4%, respectively, in the third hour compared with the CCG group. In groups CAP-250 and CAP-500, pain was reduced in the first hour by 52.8% and 69.4%, respectively, and by 28.6% and 25.8%, respectively, in the third hour compared with the CCG group. Metamizole inhibited COX-2 gene expression at a dose of 500 mg/kg in the carrageenan test. At doses of 250 and 500 mg/kg, metamizole reduced COX-2 and MPO gene expressions and oxidative stress induced by scalpel incision or carrageenan. But both doses of paracetamol were unable to suppress that parameters. CONCLUSIONS: Our results show that metamizole is more effective than paracetamol for treating surgical trauma-related pain, inflammation, and oxidative stress and hence may be a preferential drug to paracetamol.
