    In this case report we present our experience in measuring the gastric volume of a mentally-motor retarded patient for percutaneous endoscopic gastrostomy replacement. The antrum of the stomach was visualized in the subcostal region of the sagittal plane with an ultrasound probe. Anteroposterior, and right-left lateral diameters were measured. Using these measurements, the antrum cross-sectional area and then the gastric volume were calculated. Ultrasonography should be kept in mind as a good alternative approach to evaluate the gastric volume in cases with aspiration risk. © Copyright Anesthesiology and Reanimation Specialists’ Society.

    INTRODUCTION: Breast cancer is the most common type of cancer affecting women. Every year thousands of patients have surgery on breast and axillary region. Serious acute postoperative pain occurs during this surgery. In recent years the use of ultrasound in regional anesthesia practice, plane blocks has become popular in anesthesiology practice. One of them is the serratus plane block (SPB) defined by the spread of local anesthetic superficial or deep to the serratus muscle. The aim of this study is to investigate the effect of superficial SPB on postoperative opioid consumption in patients who underwent modified radical mastectomy (MRM) and axillary lymph node dissection (AD). METHODS: After ethical board approval 48 patients, between aged 18-65, ASA I-III undergoing MRM and AD surgery were randomized 2 groups. Group control ( Group C, n=24); received ultrasound guided 2 ml 0,9% salin subcutaneusly, Group SPB (Group S, n=24) received ultrasound guided SPB with 0,25 % bupivacaine 30 ml. 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). Opioid consumption, additional analgesia requirement and opioid related side effects were recorded during the first 24 hours after surgery.RESULTS: The 24-hour opioid consumption was significantly lower in the SPB group compared with the Control group (123,96 ± 72,04 mcg vs 345,83 ± 207,56 mcg respectively p<0,001). Compared with control, the VAS score was statistically lower in the SPB group during all measurements time (P < 0.05). Rescue analgesia requirement was statistically lower in the SPB group than Control group (3/24 vs 9/24 respectively, p<0.046). DISCUSSION AND CONCLUSION: Superficial SPB can be used safely in the management of pain for MRM and AD surgery as it is easy to perform, provides excellent analgesia and reduces opioid consumption. / GİRİŞ ve AMAÇ: Meme kanseri kadınları etkileyen en yaygın kanser türüdür. Her yıl binlerce hasta meme ve aksiller bölgeden cerrahi geçirmektedir. Bu cerrahi esnasında çok ciddi bir akut postoperatif ağrı meydana gelmektedir. Ultrasonografini kullanımının son yıllarda rejyonel anestezi pratiğinde artmasıyla birlikte plan blokları da oldukça popüler hale gelmiştir. Bunlardan birisi de serratus kasının üzerine veya altına lokal anestezik yayılımı ile tanımlanan serratus plane bloğudur (SPB). Bu çalışmanın amacı meme kanseri nedeniyle modifiye radikal mastektomi ve lenf nodu diseksiyonu yapılacak hastalarda yüzeyel SPB’nun postoperatif opioid tüketimine etkisini araştırmaktır. YÖNTEM ve GEREÇLER: Etik onam alındıktan sonra 18- 65 yaş arası, ASA I-III modifiye radikal mastektomi ve aksiller lenf nodu diseksiyonu yapılacak olan 48 hasta randomize olarak serratus blok (grup SPB, n=24) veya kontrol grubu (grup K, n=24) olarak iki gruba ayrıldı. SPB grubuna ultrasound eşliğinde 30 ml %0,25’lik bupivakain serratus kası üzerine SPB uygulandı. Grup K’ya ise ultrasound eşliğinde 2 ml salin subkutan cerrahi öncesi uygulandı. Postoperatif dönemde 12 saatte bir 50 mg dexketoprofen trometamol ve intravenöz fentanil ile hasta kontrollü analjezi düzenlendi. Aktif ve pasif visual analog skala (VAS) ile postoperatif analjezi değerlendirildi. Opioid tüketimi, ek analjezi ihtiyacı ve opioid ile ilişkili yan etkiler ilk 24 saatte kaydedildi. BULGULAR: SPB grubu 24 saatlik fentanil tüketimi açısından kontrol grubundan anlamlı olarak daha düşük bulunmuştur (123,96±72,04 vs 345,83±207,56 sırasıyla p<0,001). Hastaların postoperatif tüm ölçüm zamanlarında VAS değerleri Grup SPB’de kontrol grubuna göre anlamlı derecede düşüktü (p<0,05). Ek analjezik ihtiyacı; Grup SPB’de kontrol grubuna göre anlamlı derecede düşüktü (3/24 vs 9/24 sırasıyla p=0,046). TARTIŞMA ve SONUÇ: Yüzeyel SPB; MRM ve AD cerrahisinde kolay uygulanabilir olması, mükemmel bir analjezi sağlaması ve opioid tüketimini azaltmasıyla postoperatif ağrı yönetimi için güvenle kullanılabilir.

    Ultrasound guided popliteal and saphenous nerve blocks for diabetic foot surgery in a morbidly obese patient
    (Anestezi Dergisi, 2019) Gürkan, Yavuz; Karakaya, Muhammet Ahmet; Özkalaycı, Özlem; Ünlükaplan, Aytekin; Çetin, Seçil; İşgüzar, Agah; Faculty Member; Doctor; Doctor; Doctor; Doctor; Doctor; School of Medicine; N/A; N/A; N/A; N/A; N/A; Koç University Hospital; 154129; N/A; N/A; N/A; N/A; N/A
    In this case report, we shared our experience of ultrasound- guided peripheral nerve block application in a high risk patient for anesthesia undergoing diabetic foot surgery. In a patient with hypertension, diabetes mellitus, coronary artery disease popliteal and saphenous nerve blocks were performed. The blocks were performed with a 100 mm block needle, guided by ultrasound. The popliteal block was performed with 15 mL of 2% bupivacaine and 15 mL of 0.5% lidocaine with the knee in flexion and for saphenous nerve block 5 mL of 0.5% bupivacaine and 5 mL 2% lidocaine was administered. Surgery was completed without comprimising the circulatory and respiratory systems. Peripheral nerve blocks should be kept in mind as a safe alternative method of anesthesia in high risk patients.
