AIM: To analyze the demographic and clinical data of preterm or low birth weight newborns with periventricular hemorrhage. MATERIAL and METHODS: This retrospective study analyzed patients admitted to the neonatal intensive care unit of a Bahcesehir University School of Medicine -Affiliated Hospital due to preterm birth or low birth weight between June 1, 2012, and April 30, 2021. Categorical values were evaluated by Pearson chi-square or Fisher's exact test. The Mann -Whitney U test compared continuous values between the groups. Logistic regression was used to evaluate the factors that affected permanent cerebrospinal fluid (CSF) diversion. RESULTS: The study finally evaluated 180 newborns. Ninety-one newborns (50.5%) had grade I, 18 (10%) had grade II, 22 (12.2%) had grade III, and 49 (27.2%) had grade IV hemorrhage. One hundred and forty-nine patients (82.8%) were delivered by cesarean section, and 31 (17.2%) were delivered vaginally. All patients with low-grade hemorrhage who needed temporary CSF diversion eventually required permanent CSF diversion. For high-grade hemorrhage, 15 (grade III, 1; grade IV, 14) of 51 (29.4%) patients with ventricular access device (VAD) insertion required permanent CSF diversion. Fifteen (grade III, 6; grade IV, 9) of these 51 (29.4%) patients did not need permanent CSF diversion; thus, their VADs were removed. CONCLUSION: The permanent CSF diversion rate was significantly higher in the high-grade hemorrhage group, which had significantly lower weight and gestational age at birth. Moreover, only weight at VAD insertion had minimal effect on the need for permanent CSF diversion.

Spinal anesthesia in surgical treatment of lumbar spine tumors
(Elsevier, 2020) Ogrenci, Ahmet; Akar, Ezgi; Koban, Orkun; Isik, Semra; Sener, Mesut; Yilmaz, Mesut; Dalbayrak, Sedat
Objective: This study aims to show the feasibility of spinal anesthesia in lumbar spinal tumor surgery; share our data and experience. Patients and methods: : A retrospective review of 14 patients with high risk for general anesthesia due to severe comorbidities was carried out. Patients who underwent surgeries under spinal anesthesia for lumbar vertebral column or spinal cord tumors at a single center between 2007-2019 were evaluated. The final pathological diagnosis, operation time, and surgical procedures were analyzed. Also, preoperative and postoperative ad-vantages and disadvantages were determined. A comparison was performed with other 184 patients who were operated for spinal tumors in the same period under general anesthesia. Results: Maximum operation time was found 220 min, and the average operation time was 166 min. The most primary diagnosis was vertebral column metastasis. The mean age was 65.5 years. None of the patients required general anesthesia during surgery; however, two patients needed additional spinal anesthesia preoperatively, which was performed by the surgeon. Lumbar decompression and fusion were the most performed procedures. Conclusion: Spinal anesthesia is a feasible and useful method of anesthesia in lumbar spinal tumor surgery for especially elderly patients with American Society of Anesthesiologists (ASA) 3 or 4 score and high risk of general anesthesia.
