Background: Erector spinae plane block (ESPB) is a well-established method for managing postoperative and chronic pain. ESPB applications for the sacral area procedures are called sacral ESPBs (SESPBs). This cadaveric study aimed to determine the distribution of local anesthesia using the median and intermediate approaches to the SESPB.Methods: Four cadavers were categorized into the median and intermediate approach groups. Ultrasound-guided SESPBs were performed using a mixture of radiopaque agents and dye. Following confirmation of the solution distribution through computed tomography (CT), the cadavers were dissected to observe the solution distribution.Results: CT images of the median group demonstrated subcutaneous pooling of the radiopaque solution between the S1 and S5 horizontal planes. Radiopaque solution also passed from the sacral foramina to the anterior sacrum via the spinal nerves between S2 and S5. In the intermediate group, the solution distribution was observed along the bilateral erector spinae muscle between the L2 and S3 horizontal planes; no anterior transition was detected. Dissection in the median group revealed blue solution distribution in subcutaneous tissue between horizontal planes S1 and S5, but no distribution in superficial fascia or muscle. In the intermediate group, red solution was detected in the erector spinae muscle between the L2 and S3 intervertebral levels.Conclusions: Radiologic and anatomic findings revealed the presence of radiopaque dye in the superficial and erector spinae compartments in both the median and intermediate groups. However, anterior transition of the radiopaque dye was detected only in the median group.

OBJECTIVE: Erector spinae plane block is an updated method than paravertebral block, possessing a lower risk of complications. This study aimed to compare erector spinae plane and paravertebral blocks to safely reach the most efficacious analgesia procedure in laparoscopic cholecystectomy cases.

Objective: Catheter-related bladder discomfort (CRBD) due to indwelling urinary catheterization in patients undergoing transurethral resection of the prostate (TURP) is difficult to tolerate and needs to be treated. This randomized prospective study aimed to compare the efficacy of sacral erector spinae plane block (SESPB) and pudendal nerve block (PNB) in reducing the incidence and score of CRBD. Methods: This study was conducted between November and December 2023. ASA I-III, fifty-four TURP patients were divided into two groups: Group 1 received SESPB (n = 27) and Group 2 received PNB (n = 27) under ultrasound guidance at the end of surgery. The incidence of CRBD, CRBD score, numerical rating scale (NRS) score, use of rescue analgesics, block performance time, first call for analgesics, patient satisfaction, and side effects were recorded for 24 h. Results: The incidence of CRBD was lowest at 33.3% and highest at 48.1% in Group 1 and lowest at 25.9% and highest at 48.1% in Group 2, with no significant difference between the groups at all measurement times. CRBD scores and NRS scores were low and similar between the two groups. Block performance times were 9 ± 1.7 min in SESPB and 20 ± 2.5 min in PNB, and there was a significant difference between the mean times (p < 0.001). Patient satisfaction was adequate and similar in both groups. Conclusions: SESPB demonstrated a similar decreasing effect to PNB on the incidence and scores of CRBD in the first 24 h following TURP operations. The duration of SESPB administration was shorter than PNB.

BACKGROUND: Various factors contribute to the development of mortality and morbidity in hip fracture surgeries. This study aims to investigate the effects of modifiable factors such as the type of anesthesia, anesthesia management, surgical method, and timing of surgery on 30-day mortality rates, intensive care unit admissions, and complications. METHODS: A total of 400 patients who underwent hip fracture surgery between January 2021 and December 2023 at a Training and Research Hospital were retrospectively analyzed. Patients were divided into two groups: those followed in the ward, named Group 1 (n=304), and those in the intensive care unit, named Group 2 (n=96). Recorded data included demographic characteristics, American duration of surgery, blood transfusion requirements, and complications. RESULTS: Patients in Group 2 had higher mean age, comorbidity, and mortality rates compared to Group 1 (p<0.001). In terms of types of comorbidities, the rate of intensive care unit admission was higher in patients with coronary artery disease and chronic renal failure (p<0.001). Mean surgical delay and length of hospital stay were also higher in Group 2 (p<0.001). In multivariate logistic 3.188), and length of hospital stay (p=0.006, OR=1.147, CI=1.04-1.266) were determined as predictive factors for 30-day mortality. CONCLUSION: This study found that age, ASA classification, length of hospital stay, surgical method, and surgical delay were predictive factors for both morbidity and mortality. Among these, surgical delay time appears to be a modifiable parameter when all factors are considered.

Amaç: Derlenme deliryumu etiyolojisi tam olarak bilinmeyen, çoğunlukla küçük çocuklarda görülen, agresif davranışlar, göz teması eksikliği ve çevrenin farkında olmamakla karakterize bir fenomendir. Birçok sebepten kaynaklanabileceği gösterilmiş ancak en çok baş-boyun cerrahisi, inhaler ajanlar ve postoperatif ağrı suçlanmaktadır. Değerlendirmek için bazı skalalar kullanılır. Duyarlılığı en yüksek olan Pediyatrik Anestezi Deliryum Skalası olan "PAED" (Pediatric Anesthesia Delirium Scale)'dir. Preemptif analjezi, ağrı yolaklarının henüz ağrılı uyaran oluşmadan kesilerek engellenmesidir ve postoperatif analjezi için etkinliği birçok çalışma ile doğrulanmıştır. Bu çalışma: preemptif analjezi yöntemi ile azaltılan postoperatif ağrının derlenme deliryumunu azaltacağı hipotez edilerek planlanmıştır. Gereç ve Yöntemler: Etik kurul onayı alındıktan sonra adenotonsillektomi ve tonsillektomi operasyonu geçirecek, 2-7 yaş arası 96 hasta iki gruba randomize edildi. Analjezikler preemptif gruba indüksiyondan önce, intraoperatif gruba ise operasyonun başlamasından 15 dakika sonra uygulandı. Derlenme ünitesinde derlenme deliryumu PAED skalası ile, ağrı skorları çocuğun yüz ifadesi, bacakların pozisyonu, hareketleri, ağlaması ve avutulabilmesi değerlendirilerek yapılan “FLACC” (Face, Legs, Activity, Cry, Consolability) ağrı değerlendirme skalası ile değerlendirildi. FLACC>7 ağrı ve PAED> 10 derlenme deliryumu kabul edildi. Bulgular: Preemptif grupta PAED ve FLACC skorları istatistiksel olarak anlamlı düşük bulundu ancak derlenme deliryum gelişme insidansı açısından iki grup arasında sadece 5.dakikada anlamlı fark saptandı (p

Anesthesia should ideally provide an adequate level of hypnosis (sleep, unawareness/non-recall), analgesia and a suitable environment for surgery (immobility, muscle relaxation). Monitoring of the depth of anesthesia is recommended to reduce awareness during anesthesia and to improve the administration of anesthetic drugs. The bispectral index (BIS) is a numerical scale based on the analysis of EEG parameters and can reduce the adverse effects associated with over- or under-dosing of anesthetic drugs. BIS is the most studied and best documented method of cerebral monitoring This summary is based on selected literature on BIS monitoring and its combination with other monitoring modalities over the last 20 years.
