Item Effect of breast milk and sucrose on pain and perfusion index during examination for retinopathy of prematurity(2021) Turan, Ozden; Akkoyun, Imren; Ince, Deniz Anuk; Doganay, Beyza; Tugcu, A. Ulas; Ecevit, Ayse; 0000-0002-7707-1881; 0000-0002-2860-7424; 0000-0002-4369-2110; 31203685; 0000-0002-7707-1881; AAK-7713-2021; I-6746-2016Objective: The objective of this study is to investigate the effect of breast milk and sucrose on pain scores and perfusion index (PI) and to evaluate the alteration in pain and PI during retinopathy of prematurity (ROP) examination. Methods: This prospective randomized controlled study was conducted with preterm infants who were born in our hospital, hospitalized in the neonatal intensive care unit and whose gestational week was <32 weeks and birth weight was <1500 g. The preterm infants who would undergo ROP examination were allocated to three groups according to simple randomization method as follows: group 1: only local anesthetic eye drops, proparacaine HCl ophthalmic solution 0.5%, group 2: proparacaine HCl ophthalmic solution 0.5% plus breast milk, and group 3: proparacaine HCl ophthalmic solution 0.5% plus sucrose 24%. Postductal PI, transcutaneous oxygen saturation and heart rate (HR) values were measured before the eye examination (0), at the 30th, 60th, and 90th seconds (s) of the eye examination and 30 s after lasting of the examination in all infants. Pain was evaluated using Neonatal Infant Pain Scale (NIPS) during the examination. Results: Fifty-one preterm neonates were prospectively enrolled into the study. The HR was higher during and after the examination in all infants according to before the examination (p < .001). Transcutaneous oxygen saturation values significantly decreased during the examination in breast milk and sucrose groups (p = .001 and <.001, respectively). While PI was found to be lower at the 60th s compared to the 30th s of the examination in the proparacaine HCl group, no difference was found between the values before and after the examination. Perfusion index was found to significantly decrease during and after the examination compared to the values before the examination in the breast milk group. Perfusion index values were determined to significantly decrease at the 30th and 60th s of the examination in the sucrose group. The NIPS scores during the examination were determined to be higher compared to the NIPS scores before the examination in all groups (p< .001). In the intergroup comparisons, the NIPS scores were found to be higher in the sucrose group compared to the proparacaine HCl group at the 60th s of the examination and higher than that in the breast milk group at the 90th s of the examination (p = .02 and p = .01, respectively). Conclusions: The present study indicates that alterations may be seen in PI during the ROP examination; in other words, peripheral tissue perfusion could be affected. We consider that eye examination is a very painful procedure, and administering breast milk, sucrose or local anesthetic is not sufficient for reducing pain.Item Impact of Platelet Count in Retinopathy of Prematurity(2020) Keskek, Nedime Sahinoglu; Gulcan, Hande; Yilmaz, Gursel; Akkoyun, Imren; 0000-0001-8544-103X; 33389935; T-4258-2017Objectives: The aim of the study was to investigate the risk factors for retinopathy of prematurity (ROP), including platelet count. Materials and Methods: This retrospective study analyzed 137 infants in 3 subgroups: no ROP; mild RAP, and severe ROP requiring laser treatment (type 1 ROP). A retrospective review of records was performed and statistical analysis of possible risk factors for ROP including platelet count was evaluated by using logistic regression. Results: Birth weight (BW), gestational age (GA), and low platelet count in the first week after birth were significant risk factors for developing ROP (p=0.038, 0.02, and 0.004, respectively). BW, GA, ventilation, and lower platelet count were associated with progression to type 1 ROP (p=0.004; 0.027, and 0.021, respectively). Conclusion: Lower platelet count in the first week after birth is a risk factor for ROP development in addition to the previously established factors of ventilation need, low BW, and low GA.Item Favorable outcomes in the treatment of aggressive posterior retinopathy of prematurity(2019) Sahinoglu-Keskek, Nedime; Akkoyun, Imren; Torer, Birgin; 0000-0001-8544-103X; 31718282; T-4258-2017Objectives: To report the results of intravitreal ranibizumab injection as primary therapy in aggressive posterior retinopathy of prematurity, the process of the disease, and the additive treatments performed. Methods: This retrospective case review included 15 eyes of 8 premature babies with aggressive posterior retinopathy of prematurity who were initially treated with intravitreal ranibizumab injection. The documented data were gestational age, birth weight, gender, postmenstrual age at intravitreal ranibizumab injection, zone of retinopathy of prematurity, reactivation time of disease, iris neovascularization, retinal hemorrhage, anatomical outcome, and additional treatment. Results: Median gestational age at birth was 26 (range, 23-27)weeks, birth weight was 730 (range, 550-970)g, and postconceptional age at aggressive posterior retinopathy of prematurity diagnosis and intravitreal ranibizumab injection was 35 (range, 33-35)weeks. Intravitreal ranibizumab injection was performed as primary treatment. Two eyes necessitated a second intravitreal ranibizumab injection. The reactivation of retinopathy of prematurity was 5 (range, 3-7)weeks after intravitreal ranibizumab injection. Recurrence of the disease in Zone II was treated with laser photocoagulation. A favorable outcome was obtained in all eyes (100%). Conclusion: Aggressive posterior retinopathy of prematurity is a serious, rapidly progressing form of retinopathy of prematurity that requires quick and proper management. This study indicates that primary treatment with ranibizumab and laser photocoagulation on recurrence provide favorable anatomical outcomes.
