Background and Aims: Serratus posterior superior intercostal plane block (SPSIPB) is a novel technique that can provide analgesia in the hemithorax, shoulder, and back of the neck. This study aimed to evaluate the post-operative analgesic effect of SPSIPB in patients undergoing video-assisted thoracoscopic surgery (VATS). Methods: It is a double-blind, randomised controlled trial. Twenty-four adult patients who underwent VATS via the uniportal technique were randomised into two groups: the SPSIPB group (n = 12) received SPSIPB along with intravenous patient-controlled analgesia (PCA) with tramadol, whereas the control group (n = 12) received only PCA with tramadol. At the end of the surgery, patients in the SPSIPB group received a unilateral SPSIPB under ultrasound guidance with the use of 30-mL bupivacaine 0.25%. The primary outcome was the numerical rating scale (NRS) scores of the patients. Secondary outcomes included the amount of tramadol and rescue analgesic (paracetamol) consumed by the patients, followed up for post-operative 24 hours. Categorical variables were compared using the Chi-Square Test. Mann–Whitney U Test was used to compare groups of variables that were not normally distributed. Results: The SPSIPB group had lower NRS values during post-operative 24 hours ( P < 0.001). Mean (standard deviation) total tramadol consumption was 58.33 (26.23) mg in the SPSIPB group and 144.17 (13.11) mg in the control group ( P < 0.001). Rescue analgesic need was lower in the SPSIP group in the first 18 post-operative hours ( P < 0.05). Conclusion: Serratus posterior superior intercostal plane block provides good analgesia in the thoracic region after video-assisted thoracoscopic surgery.

Serratus posterior superior intercostal plane block (SPSIPB) is a novel technique that provides analgesia in shoulder, hemithorax and in the back of the neck. In this study, the efficacy of this block on postoperative pain and quality of recovery is reported in ten consecutive patients who had undergone reduction mammoplasty. Blocks were performed bilaterally with 30 ml 0.25 % bupivacaine for each side, at the end of surgery. Cumulative tramadol consumption and numerical rating scale (NRS) scores during rest (static) and coughing (dynamic) were assessed within the first postoperative 24 hours. Mean total tramadol consumption was 39 +/- 9.94 mg. NRS scores above 4 were observed in 5 patients in the dynamic NRS assessment at the postoperative 1st hour, while static and dynamic NRS scores were <= 4 at other durations. SPSIPB may play a part in postoperative multimodal analgesia following mammoplasty in the future and may reduce total analgesic consumption.

Objective: The aim of this study was to determine the effect of adding dexmedetomidine to intra-articular levobupivacaine on postoperative pain levels and analgesic requirements following arthroscopic meniscectomy. Methods: A total of 60 American Society of Anesthesiologist physical status I-II patients, aged 20 to 62 years, and scheduled for arthroscopic partial meniscectomy under general anesthesia were included in this study. All the patients were randomly assigned to one of four groups (15 patients in each group): Group 1 (8 male, 7 female; mean age = 46.70 ± 13.13 years; 0.9% isotonic 20 ml), group 2 (7 male, 8 female; mean age = 42.60 ± 12.18 years; levobupivacaine 0.5 mg/kg plus 0.9% isotonic), group 3 (8 male, 7 female; mean age = 43.80 ± 12.63 years; 1μg/kg dexmedetomidine plus 0.9% isotonic), and group 4 (7 female, 8 male; mean age = 40.40 ± 11.79 years; levobupivacaine 0.5 mg/kg plus 1μg/kg dexmedetomidine and 0.9% isotonic). All medications were administered at the end of arthroscopic surgery. Pain levels were measured using a Visual Analogous Scale (VAS) and Verbal Rating Scale (VRS) at postoperative 1, 2, 4, 6, 12, and 24 hours. Results: VAS scores at rest were significantly lower in Group 4 at postoperative 1th, 2nd, 4th, 6th,12th, and 24th hours than in other groups. The time to take the first analgesic was significantly higher in Group4 (964 ± 288 min), and total analgesic consumption was significantly lower in Group 4 compared to those of other groups. Conclusion: Although administration of intra-articular dexmedetomidine alone may have a weaker effect than intra-articular levobupivacaine on postoperative pain relief after arthroscopic partial meniscectomy, adding dexmedetomidine to intra-articular levobupivacaine may increase the durationand quality of postoperative analgesia without any side effect.

Postherpetic neuralgia results from varicella-zoster virus reactivation post–chickenpox infection, manifesting as persistent and severe pain lasting a minimum of 3-mo post–herpes zoster onset. Traditional postherpetic neuralgia management comprises antiviral, analgesic medications, corticosteroids, and various agents. Ultrasound-guided nerve blocks have recently emerged as a promising postherpetic neuralgia treatment. In a case involving a 58-year-old man with severe thoracic herpes zoster lesions, the serratus posterior superior intercostal plane block was employed under ultrasound guidance, significantly reducing pain scores and enhancing quality of recovery. This study underscores serratus posterior superior intercostal plane block’s secure, effective role in managing thoracic herpes zoster, and mitigating postherpetic neuralgia risk. This case report represents the pioneering application of serratus posterior superior intercostal plane block for postherpetic neuralgia, offering a promising avenue for relieving patients suffering from this condition.

Objective: To determine the effect of single-shot interscalene brachial plexus (ISBP) block on intracranial pressure (ICP) by eval-uating the extravascular volume effect of the medicine on the internal jugular vein (IJV). Study Design: Interventional study. Place and Duration of Study: Department of Anaesthesiology and Reanimation, Sivas Cumhuriyet University, Sivas, Turkey, from January to June 2022. Methodology: Thirty-four patients were included in this prospective clinical study. All patients had single-shot ISBP block with 25 ml of local anaesthetic. Optic nerve sheath diameter (ONSD), maximum (Dmax) and minimum (Dmin) diameters of IJV and IJV collapsibility index (IJV-CI) were recorded before the block (basal), 20 minutes, and 60 minutes after the block. Results: Twenty-nine patients had higher ONSD values at 60th minute compared to their basal values. There were negative correlations between the changes of ONSD and IJVCI (r=0.616, p<0.001) and ONSD and Dmax (r=0.581, p<0.001) in time period between basal and 20th minute. There were negative correlations between the changes of ONSD and IJVCI (r=0.518, p=0.002), ONSD and Dmax (r=0.664, p<0.001) in time period between basal and 60th minute. Conclusion: Single-shot ISBP block with 25 ml of local anaesthetic may be a factor that increases ICP. Repeated intraoperative ONSD measurements are recommended in patients operated with ISBP block.
