Item The Application of Infraclavicular Brachial Plexus Block with Retroclavicular Approach for Arterio-Venous Fistula Aneurysm(2021) Karaca, Omer; Pinar, Huseyin Ulas; 33913132Infraclavicular block provides adequate anesthesia to the arm, forearm, and antecubital region. There are many different approaches to infraclavicular brachial plexus block. Corocoid approach which is mostly preferred is not appropriate in some cases that needle orientation disappear. In this case report, we performed a newly defined retroclavicular approach to infraclavicular brachial plexus block and discussed in the light of information in literature. The patient who has 79 year old man, 29.36 body mass index, American Society of Anesthesiologists 3 with chronic renal failure was admitted to the operation room with complaint of aneurysmatic arteriovenous fistula in the left antecubital area. We planned the infraclavicular brachial plexus block with retroclavicular approach for better visibility of need le. The needle insertion point was posterior to the clavicle and the needle was advanced from cephalad to caudal. The block was effectuated after median nerve stimulation as the needle was advanced toward posterior of axillar artery. In our case with excess weight and life-threatening disease, it is highly reliable to perform infraclavicular block with retroclavicular approach indicated spread of local anesthetic, needle tip, and orientation without damage to nerve and vascular structures under ultrasound-guided.Item Comparison of Ultrasound-Guided Erector Spinae Plane Block and Subcostal Transversus Abdominis Plane Block for Postoperative Analgesia after Laparoscopic Cholecystectomy: A Randomized, Controlled Trial(2021) Ozdemir, Halime; Araz, Coskun; Karaca, Omer; Turk, Emin; 34085883; 0000-0001-7515-4264Purpose Laparoscopic cholecystectomy causes moderate to severe pain despite its minimally invasive nature. This study was performed to compare the efficacy of the bilateral erector spinae plane block (ESPB) and the subcostal transversus abdominis plane block (STAPB) under ultrasound guidance. Methods 64 patients were included in this prospective, randomized study. The patients were allocated into two groups as those receiving ESPB (n = 32) and those receiving STAPB (n = 32). Pain scores at rest and during movement, fentanyl requirement, postoperative walking time, and duration of hospital stay were compared. The complications which related to block were also recorded. Results In the ESPB group, the Numeric Rating Scale (NRS) scores at rest were lower at hour 0 [at the time of post-anesthetic care unit (PACU) admission] and postoperative hours 2, 4, 6, and 12 (p < 0.05). In the same group, the NRS scores at movement were lower at hours 0, 2, 4, 6, 12, and 24 (p < 0.05). In the ESPB group, the time to first analgesic need was longer (p < 0.05), intraoperative and postoperative Fentanyl requirement (p < 0.0001 for both) and PACU rescue analgesic requirement were lower (p < 0.05), the lengths of PACU and hospital stay were shorter (p < 0.0001), and unassisted walking time was shorter (p < 0.0001). There were no complications related to the block in either group. Conclusion Bilateral ultrasound-guided ESPB provides superior analgesia after laparoscopic cholecystectomy surgery compared to STAPB and further reduces unaided walking time and hospital stay.Item Ultrasound-guided bilateral greater occipital nerve block on headache seen after endovascular treatment of ruptured or unruptured intracranial aneurysms: A case report(2020) Dogan, Rafi; Pinar, Wiseyin Ulas; Karaca, Omer; Karakoc, Fatma; 0000-0002-5904-3932; 0000-0003-0473-6763; 33398867; AAJ-7677-2021Headache is a common symptom in subarachnoid hemorrhage (SAH). Often, pain control is difficult and opioid use can have a complicated effect on the patient's state of consciousness. In this study of 2 cases, opioid consumption was reduced while effective pain control of headache occurring after endovascular treatment of an intracranial aneurysm was achieved using an ultrasound-guided, bilateral greater occipital nerve (GON) block. Case 1 was a 59-year-old male patient with a Glasgow Coma Scale (GCS) of 13 who was diagnosed with Fisher scale grade 3 SAH. Coiling and stenting were performed for an anterior communicating artery aneurysm. Cerebrospinal fluid drainage was provided with a lumbar spinal catheter. Case 2 was a 55-yearold male patient with a GCS of 15 who underwent coiling of a fusiform aneurysm in the left basilar artery and stenting of the stenotic region due to a basilar artery aneurysm. After the procedure, the visual analog score (VAS) of the patients was 9 and 7, respectively, and a bilateral GON block was performed with ultrasound guidance.The VAS score of both patients decreased to 3 and did not exceed 3 during follow-up in the intensive care unit, eliminating the need for additional analgesics. A bilateral GON block provided effective analgesia and significantly reduced the need for other pain relief in both cases.Item The efficacy of ultrasound-guided type-I and type-II pectoral nerve blocks for postoperative analgesia after breast augmentation: A prospective, randomised study(2019) Karaca, Omer; Pinar, Huseyin U.; Arpaci, Enver; Dogan, Rafi; Cok, Oya Y.; Ahiskalioglu, Ali; 0000-0002-8467-8171; 0000-0003-0473-6763; 0000-0003-1933-2075; 29627431; B-7473-2016; Q-2420-2015; AAU-6923-2020Purpose: The present study was planned to evaluate the efficacy and safety of ultrasound-guided Pecs I and II blocks for postoperative analgesia after sub-pectoral breast augmentation. Methods: Fifty-four adult female patients undergoing breast augmentation were randomly divided into two groups: the control group (Group C, n = 27) who were not subjected to block treatment and Pecs group (Group P, n = 27) who received Pecs I (bupivacain 0.25%, 10 mL) and Pecs II (bupivacain 0.25%, 20 mL) block. Patient-controlled fentanyl analgesia was used for postoperative pain relief in both groups, and the patients were observed for the presence of any block-related complications. Results: The 24-h fentanyl consumption was smaller in Group P [mean +/- SD, 378.7 +/- 54.0 mu g and 115.7 +/- 98.1 mu g, respectively; P < 0.001]. VAS scores in Group P were significantly lower at the time of admission to the post-anaesthetic care unit and at 1, 2, 4, 8, 12, and 24 h (P < 0.001). The rates of nausea and vomiting were higher in Group C than in Group P (9 vs 2, P = 0.018). Hospital stay duration was shorter in Group P than in Group C (24.4 +/- 1.2 h vs 27.0 +/- 3.1 h, P < 0.001). No block-related complications were recorded. Conclusions: Combine used of Pecs I and II blocks provide superior postoperative analgesia in patients undergoing breast augmentation and shortens hospital stay.

The present study was planned to compare the efficacy of the combination of pregabalin plus iv ibuprofen. Methods: 58 patients were included in this prospective, randomized, double-blinded study. The pregabalin group (Group P, n = 29) received 150 mg pregabalin, the pregabalin plus ibuprofen group (Gropu PI, n = 29) received 150 mg pregabalin and 400mg iv ibuprofen before surgery. Postoperative fentanyl consumption, additional analgesia requirements and PACU stay were recorded. Postoperative analgesia was performed with patient-controlled IV fentanyl. Results: VAS scores in the group PI were statistically lower at PACU, 1and 2 hours at rest, at PACU, 1, 2, 4, 12 and 24 hours on movement compared to the group P (P < 0.05). Opioid consumption was statistically significantly higher in the group P compared to the group PI (130.17 +/- 60.27 vs 78.45 +/- 60.40 mu q, respectively, P < 0.001) and reduced in the 4th 24 hours by 55% in group PI. Rescue analgesia usage was statistically significantly higher in the group P than in the group PI (16/29 vs 7/29, respectively, P < 0.001). Four patient in the group PI did not need any opioid drug. Besides, PACU stay was shorter in the group PI than the group P (10.62 +/- 2.38 vs 15.59 +/- 2.11 min, respectively, P < 0.001). Conclusion: Preemptive pregabalin plus iv ibuprofen in laparoscopic cholecystectomy reduced postoperative opioid consumption. This multimodal analgesic aproach generated lower pain scores in the postoperative period.Item Continuous ultrasound guided erector spinae plane block for the management of chronic pain(2019) Ahiskalioglu, Ali; Alici, Haci Ahmet; Ciftci, Bahadir; Celik, Mine; Karaca, Omer; 0000-0003-1933-2075; 29253539; AAU-6923-2020Item Less painful ESWL with ultrasound-guided quadratus lumborum block: a prospective randomized controlled study(2019) Yayik, Ahmet Murat; Ahiskalioglu, Ali; Alici, Haci Ahmet; Celik, Erkan Cem; Cesur, Sevim; Ahiskalioglu, Elif Oral; Demirdogen, Saban Oguz; Karaca, Omer; Adanur, Senol; 0000-0003-1933-2075; 31496381; AAU-6923-2020Objectives: Extracorporeal shock wave lithotripsy (ESWL) has been widely used for the treatment of urinary tract stones and is usually administered as an outpatient procedure, although the vast majority of patients do not tolerate it without sedoanalgesia. The quadratus lumborum block (QLB) is a newly-defined technique for abdominal surgery. The aim of this study was to evaluate the analgesic efficacy of ultrasound-guided QLB in ESWL. Materials and methods: Forty patients, aged 18-65, with ASA physical status I-II and scheduled for ESWL were randomly assigned to Group C (control group) and Group QLB (treatment group). Group QLB received single-shot USG-guided transmuscular QLB with 10 ml of 0.5% bupivacaine and 10 ml of 2% lidocaine before a 20-min ESWL procedure. No intervention was performed on Group C. Visual analogue scale (VAS) scores, opioid consumption, patient satisfaction, ESWL and stone details were recorded. Results: VAS scores were significantly lower in Group QLB at all time intervals (p < 0.05). Fentanyl consumption during ESWL was significantly lower in Group QLB than in Group C (p < 0.001). The fragmentation success rate was significantly higher in Group QLB than in Group C (19/20 vs 14/20, respectively, p = 0.046). Patient satisfaction was also higher in Group QLB (p = 0.011). Conclusions: This study shows that QLB provided adequate analgesia for ESWL and that it reduced extra opioid consumption significantly compared to the control group.Item Efficacy of ultrasound-guided bilateral erector spinae plane block in pediatric laparoscopic cholecystectomy: Case series(2019) Karaca, Omer; Pinar, Huseyin Ulas; 0000-0003-0473-6763; 31741347; Q-2420-2015Postoperative opioid administration can cause various side effects, such as drowsiness, respiratory distress, postoperative nausea, and vomiting. The use of non-opioid medications as part of a multimodal analgesia method has been increasingly suggested in the management of acute postsurgical pain. Erector spinae plane block (ESPB), which is a regional anesthesia technique, blocks both visceral and somatic nerve fibers.Though it is infrequently used in young patients, presently described is a series of cases in which ESPB was successfully used in the performance of pediatric laparoscopic cholecystectomy. Ultrasound-guided bilateral ESPB was performed on 4 patients who underwent a laparoscopic cholecystectomy. An injection of 0.25% bupivacaine was administered into the interfascial area on each side in the pre-incisional period after the anesthesia induction (total anesthetic: 2.5 mg/kg). Postoperative pain control was planned at 10 mg/kg intravenous paracetamol every 8 hours. Numeric rating scale pain scores were less than 3 points in the post-anesthetic care unit, and at 1, 2, 4, 8, 12, and 24 hours. No rescue analgesic (1 mg/kg tramadol) was needed. None of the typical complications, such as drowsiness or nausea, were observed and no block-related complications were recorded. Bilateral ESPB that is a part of multimodal analgesia regimen can provide effective analgesia for pediatric laparoscopic cholecystectomy patients in the first 24 hours postoperatively.Item Ultrasound-Guided versus Conventional Caudal Block in Children: A Prospective Randomized Study(2019) Karaca, Omer; Pinar, Huseyin Ulas; Gokmen, Zeynel; Dogan, Rafi; 0000-0003-0473-6763; 0000-0003-1933-2075; 30602192; Q-2420-2015; AAU-6923-2020Background Injection to the accurate area without any complications is the main factor for the efficiencies of caudal block. The aim of this study was to compare success and the complications of conventional and ultrasound method for caudal block in children. Materials and Methods Two-hundred sixty-six American Society of Anesthesiologists (ASA) category 1 children aged between 6 months and 6 years undergoing hypospadias, circumcision, or both surgeries were randomly allocated two groups (Group C or Group H, n =133). About 0.25% bupivacaine with 1/200000 adrenaline (total volume: 0.5 mL/kg) was injected after the needle was inserted into the sacral canal in Group C, or right after the needle pierced the sacrococcygeal ligament under longitudinal ultrasound view in Group H. Success rate of block, block performing time, number of needle puncture, success at first puncture, complication rate, age and weight of the patients encountering these complications were recorded. Results The success rate of block was similar between two groups (94.7% in Group C vs 96.2% in Group U, p >0.05). Success at first puncture was higher in Group U than in Group C (90.2 vs 66.2%, respectively; p <0.001). Number of needle puncture, blood aspiration, subcutaneous bulging, and bone contact was higher in Group C but none in Group U ( p <0.001) and these complications were occurred in children weighing<16kg and less younger than 6 years old. Conclusion We observed that the complications were not encountered, number of needle puncture was lesser, and the success rate of first puncture was higher under ultrasound with longitudinal view.Item The effect of pregabalin on tourniquet-induced ischemia-reperfusion injury: a prospective randomized study(2019) Karaca, Omer; Pinar, Huseyin Ulas; Ozgur, Ahmet Fevzi; Kulaksizoglu, Sevsen; Dogan, Rafi; 0000-0003-0473-6763; 31655508; Q-2420-2015Background/aim: The aim of this study was to investigate the efficacy of pregabalin on ischemia-reperfusion injuries. Materials and methods: Fifty-four patients were randomly assigned into 2 groups. A 150-mg tablet of pregabalin was given the night before and then 1 h before the operation for patients in Group P (pregabalin group, n = 27). A placebo was given to patients in Group C (control group, n = 27) at the same times. After combined spinal-epidural anesthesia was performed, venous blood samples were taken before tourniquet inflation (t(1)), just before tourniquet deflation (t(2)), and 20 min after tourniquet deflation (t(3)) for the analysis of total antioxidant status (TAS), total oxidant status (TOS), catalase (CAT), and ischemia-modified albumin (IMA). Results: There was no significant difference in TAS levels between the groups for the t(3) period. However, the TAS in Group P was significantly higher in the t(3) period than the t(2) period (mean +/- SD, 0.46 +/- 0.1 vs. 0.38 +/- 0.2 mmol of Trolox equivalent/L, respectively; P < 0.05). The CAT level in the C period was significantly higher in Group P than Group C (mean +/- SD, 53.04 +/- 32.1 vs. 35.46 +/- 17.2 mu mol/formaldehyde, respectively; P < 0.05). In the t(3) period, the TOS was significantly lower in Group P than Group C (mean +/- SD, 11.97 +/- 5 vs. 18.29 +/- 9.9 pg/mL, respectively; P < 0.05). The TOS in Group P was significantly lower in the t(3) period than the t(2) period (mean +/- SD, 11.97 +/- 5 vs. 18.98 +/- 10.7 pg/mL, respectively; P < 0.0001). Conclusion: Pregabalin has no marked antioxidant activity, but it contributes to the antioxidant defense system of an organism.
