Retrospective cohort evaluation of postnatal growth and retinopathy of prematurity (G-ROP) criteria in a tertiary centre in Turkey.

PURPOSE: The postnatal growth and retinopathy of prematurity (G-ROP) study has proposed a new model to increase the effectiveness of screening retinopathy of prematurity (ROP). The present study aimed to evaluate the effectiveness of the G-ROP model in a tertiary centre in Turkey. METHODS: The medical records of infants screened for ROP in our hospital between January 2018 and December 2022 were reviewed retrospectively. Babies with a documented ROP result and regular body weight measurements up to the 40th day of life were included in the study, and the G-ROP model was applied. The sensitivity of the G-ROP prediction model in detecting treated ROP, Type 1 ROP, Type 2 ROP, and low-grade ROP and the reduction in the number of babies to be screened by applying the model were calculated. RESULTS: The G-ROP model was applied to a total of 242 infants. While 194 babies were determined for screening, 22 of them were treated. The sensitivity to predict treated ROP was 100%, and the specificity was 21.8%. The model successfully predicted all cases of Type 1 ROP in the cohort, while the sensitivity was 90.9% for Type 2 ROP and 90.7% for low-grade ROP. The G-ROP model reduced the number of infants requiring screening by 19.8% in our study. CONCLUSIONS: The G-ROP model was successfully validated in our cohort in detecting treated ROP and Type 1 ROP, reducing the number of infants requiring screening by approximately 1 in 5.

Reversal of Rocuronium-Induced Neuromuscular Blockade by Sugammadex Under Sevoflurane and Desflurane Anesthesia in Children.

OBJECTIVE: In children, neuromuscular blockers may have different effects with various inhalation agents and incomplete reversal of the blockade continues to be a problem. The aim of the study is to observe the effects of sugammadex on reversing the blockade by a single dose of rocuronium, the peak inspiratory pressure, hemodynamic parameters in children under sevoflurane and desflurane anesthesia. MATERIALS AND METHODS: One hundred forty-eight children aged 2-10 years old, to be operated under shortterm general anesthesia, were enrolled in this prospective randomized controlled trial. After induction, the patients were intubated at the end of TOF (Train-of-four) ratio of 1.0-0. The time taken until TOF reached 0.25 was recorded, and 2 mg/kg sugammadex was administered to the patients. The period until the TOF was at least 0.9 and in the first 10 minutes after sugammadex injection, peak inspiratory pressure, the systolic-diastolic arterial pressure, and the heart rate were monitored and possible side effects were observed in the recovery room. RESULTS: Following the injection of sugammadex, the time taken for TOF of 0.25 to reach >0.9 was significantly shorter in the 2-4-year-old age group under sevoflurane anesthesia. After sugammadex injection, a small but statistically significant increase in peak inspiratory pressure values was observed in Group D at the 2nd, 5th, and 10th minutes. CONCLUSION: Rapid and complete recovery was achieved from the block induced by a single dose of 0.6 mg/ kg rocuronium by the use of sugammadex which did not give rise to any side effects.

Challenging Anaesthesia Management of a Patient with Fryns Syndrome: A Case Report.

Fryns syndrome cases with variable characteristics require careful preoperative evaluation and have challenges for airway management. Craniofacial anomalies can complicate both ventilation and intubation. Extubation can also be problematic because of limited pulmonary reserves.

HSV-1 Encephalitis Presenting with Diplopia: Effects of Infection or Autoimmunity?

This report describes a case in which diplopia was developed as a finding of postinfectious anti- N -methyl- d -aspartate receptor encephalitis. Infectious encephalitis, especially herpes simplex virus, is essential as it is one of the triggers of autoimmune encephalitis. Even if the cases present unexpected clinical findings, we should be vigilant in terms of autoimmune processes, such as diplopia seen in our case.

Pudendal nerve block for circumcision of pediatric patient with Pierre Robin Sequence: case report

Abstract Pierre Robin Sequence (PRS) is a congenital condition characterized by micrognathia, glossoptosis, and cleft palate that presents with airway obstruction and developmental delay with or without other congenital anomalies. These patients' anesthesia management is challenging because of difficult ventilation and intubation. Regional anesthesia methods should be considered for these patients on a case-by-case basis. This report presents primary use of regional anesthesia for circumcision of a 9-year-old boy with PRS.

A prospective long-term evaluation of the ocular findings of children followed with the diagnosis of multisystem inflammatory syndrome (long-term evaluation of ocular findings following MIS-C).

BACKGROUND/OBJECTIVES: The most frequently reported ocular finding in the acute phase of the multisystem inflammatory syndrome in children (MIS-C), is conjunctivitis. More rarely, punctuate epitheliopathy, anterior uveitis and optic disc oedema can be seen. We aimed to investigate the acute and long-term ocular effects of MIS-C. SUBJECTS/METHODS: Cases aged 1 month to 18 years who were diagnosed with MIS-C between January 2022 and June 2022 in the Department of Pediatric Infectious Diseases in our hospital were included in the study. Ophthalmological examinations were performed immediately after diagnosis, at one month, three months, and six months. RESULTS: Males consisted of 64.7% of the 34 cases included in the study and the mean age was 8.68 ± 4.32 years (min-max:2-17). In the first examination, conjunctivitis was observed in 6 (17.6%), punctuate epitheliopathy in 4 (11.7%), and subconjunctival haemorrhage in 3 (8.8%) patients. Two patients (5.8%) had optic disc oedema. No pathological anterior or posterior segment findings were observed in the sixth-month examination. The relationship between subconjunctival haemorrhage and intensive care hospitalisation was statistically significant (p = 0.014). Also, all patients with subconjunctival haemorrhage were clinically classified as severe MIS-C (p = 0.002). CONCLUSION: Although pathological ocular findings were observed in the acute phase of the disease, all of them were found to be improved at the sixth-month follow-up. The most striking finding of our study is that cases with subconjunctival haemorrhage were clinically more severe, and all patients needed intensive care. This study may be informative in establishing ocular follow-up protocols that are expected to be carried out in the acute period and in the follow-up of these patients.

Effect of paediatric caudal injection volume on optic nerve sheath diameter and regional cerebral oximetry: A randomised trial.

BACKGROUND: Caudal injections commonly used for neuraxial anaesthesia in children can displace cerebrospinal fluid cranially causing safety concerns in terms of raised intracranial pressure. Optic nerve sheath diameter (ONSD) is a noninvasive surrogate for the measurement of intracranial pressure. Regional cerebral oximetry (CrSO 2 ) can monitor brain oxygenation, which may decrease by a reduction in cerebral flow due to increased intracranial pressure. OBJECTIVES: Comparing how caudal injection volumes of 0.8 and 1.25 ml kg -1 influence ONSD and CrSO 2 within the first 30 min after injection. DESIGN: Prospective, randomised and parallel group trial. SETTING: Operating room. PATIENTS: Fifty-eight elective paediatric surgical patients between ages 1 and 7 years old, ASA class I or II, without previous intracranial or ocular pathology and surgery appropriate for single - shot caudal anaesthesia. INTERVENTION: Single-shot caudal anaesthesia with 0.8 ml kg -1 (group L, n  = 29) and 1.25 ml kg -1 (group H, n  = 29) of 2 mg kg -1 bupivacaine solution. MAIN OUTCOME MEASURES: Optic nerve sheath diameter measured with ultrasonography and regional cerebral oximetry measured by near - infrared spectroscopy before (NIRS), immediately after, 10, 20 and 30 min after the block. RESULTS: Mean ONSD values increased from a baseline of 4.4 ±â€Š0.2 mm to a maximum of 4.5 ±â€Š0.2 mm 20 min after injection in group L and from a baseline of 4.5 ±â€Š0.3 mm to a maximum of 4.8 ±â€Š0.3 mm 10 min after injection in group H. Eight of 29 patients in group H and none in group L had an ONSD increase by more than 10%. Both groups had a reduction of less than 2.5% in CrSO 2 . CONCLUSION: Caudal injection with 1.25 ml kg -1 increased ONSD, an indirect measurement of ICP, more than 0.8 ml kg -1 and neither volume caused a clinically important reduction in CrSO 2 . TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04491032.

Does magnetic resonance imaging increase core body temperature in children? Results of the administration of propofol and ketofol: a randomized clinical study.

BACKGROUND AND OBJECTIVES: Magnetic resonance imaging (MRI) may cause a temperature increase in the imaging area, while intravenous anesthetics may develop a tendency for hypothermia, especially in the pediatric population. The effect of different anesthetics on core body temperature in children during these procedures remains controversial. We examined the effect of propofol and ketofol on core body temperatures in a pediatric population during MRI. Our hypothesis was that the increase in body temperature will be more prominent in pediatric patients receiving ketofol than in those receiving propofol. METHODS: This was a randomized, prospective, double-blind study in pediatric patients aged 6 months to 10 years. The patients were American Society of Anesthesiologist (ASA) physical class I-II who had undergone MRI under anesthesia at the Cerrahpasa School of Medicine, MRI Area, between August 2014 and February 2016. Patients were assigned to one of two groups: Group I (propofol group) and Group II (ketofol group). MRIs were performed with a 1.5 Tesla (T) device. Bilateral tympanic membrane temperature measurements before and after the procedure were performed. RESULTS: Body temperature decreased in both groups after MRI. Clinically significant hypothermia or hyperthermia was not observed in any of the patients. CONCLUSION: Temperature monitoring is not necessary for every patient being imaged. However, temperature changes should be closely monitored in high-risk patients.

Complicaciones durante la esofagoscopía con o sin dilatación con globo y con anestesia general en pacientes pediátricos: estudio prospectivo y observacional / Complications during esophageal endoscopy with or without baloon dilation under general anesthesia in pediatric patients: a prospective and observational study

Antecedentes. Durante una esofagoscopía en niños, pueden ocurrir complicaciones durante la dilatación. Identificamos alteraciones cardiorrespiratorias durante la esofagoscopía con o sin dilatación con globo y las complicaciones posoperatorias, en niños con anestesia. Métodos. Estudio prospectivo, observacional de procedimientos endoscópicos en niños de 0-16 años. Se dividieron en dos grupos: con endoscopía-dilatación (Grupo ED) y dilatación con globo por estenosis esofágica, y con endoscopía sin dilatación (Grupo E): endoscopía diagnóstica, esofagoscopía de control o escleroterapia. Registramos parámetros hemodinámicos y ventilatorios y las complicaciones durante la endoscopía, la dilatación y el seguimiento de dos horas en la sala de recuperación. Resultados. Incluimos 102 procedimientos en 60 pacientes. La presión inspiratoria máxima (PIM) aumentó significativamente en ambos grupos (p < 0,001) y aumentó significativamente durante el procedimiento en el grupo ED (p < 0,001). La diferencia en la PIM antes y después de la endoscopía se correlacionó negativamente en ambos grupos. Al subdividir los grupos según el punto de corte de 2 años para comparar la diferencia en la PIM antes y después de la endoscopía, la PIM aumentó de manera estadísticamente significativa en ambos grupos en los menores de 2 años. En el grupo ED, la frecuencia cardíaca aumentó estadísticamente significativa (p < 0,001). Conclusión. Durante la endoscopía, la PIM aumentó en niños con o sin dilatación con globo, especialmente en el grupo ED, y fue mayor en los niños más pequeños. Es necesario observar y tratar atentamente las complicaciones cardiorrespiratorias graves durante la dilatación con globo y con anestesia general.

Background. Complications can occur during esophagoscopy as a result of applied procedure in children, especially during dilation techic. Our aim was to identify cardio-respiratory alterations during esophagoscopy with or without baloon dilation under anesthesia in children, and to investigate the postoperative complications. Methods. Prospective, observational study of endoscopic procedures in patients 0-16 years. The patients were divided into two groups: the endoscopy-dilation group (Group ED: endoscopy and balloon dilation due to esophageal stricture) and endoscopy without dilation (Group E: endoscopy for diagnostic reasons, control esophagoscopy or sclerotherapy). Hemodynamic and ventilatory parameters alterations and complications during endoscopy, dilation and two-hours follow-up time in the postoperative recovery room were recorded. Results. 102 procedures in 60 patients were included. Peak inspiratory pressure (PIP) values significantly increased after endoscopy in both groups (p<0.001). There was a significant increase in mean PIP values in the dilation group during the procedure (p<0,001). The difference in PIP values before and after the endoscopy was negatively correlated with age in both groups. When the groups were subdivided taking two years of age as a cut-off point in comparing PIP difference before-after endoscopy, PIP increase was statistically significant in both groups under two-years old. In the dilation group, statistically significant increase of HR was detected during the procedure (p<0,001). Conclusion. During endoscopy PIP increased in patients with or without baloon dilation especially in the dilation group. PIP increase was higher in younger children. Severe respiratory and cardiovascular complications during balloon dilation under general anesthesia should be carefully observed and managed.

Pudendal Nerve Block Versus Penile Nerve Block in Children Undergoing Circumcision.

PURPOSE: Penile nerve block is the most popular nerve block for the circumcision in pediatric patients. This study aimed to compare the analgesic efficiency of penile nerve block and the pudendal nerve block on postoperative pain and additional analgesic requirements in children undergoing circumcision. MATERIAL AND METHODS: This prospective randomized double-blind study enrolled 85 children, aged 1 to10 years, undergoing circumcision. The patients were randomly divided into two groups either receiving dorsal penile block group (PNB-Group) or pudendal nerve block (PDB-Group). In the PNB-Group, 0.3 ml/kg 0.25 % bupivacaine was used; and, in the PDB-Group, 0.3 ml/kg bupivacaine was applied with nerve stimulator at a concentration of 0.25%. In the postoperative period, the modified CHEOPS pain scale scoring and additional analgesic demand were evaluated at the 5th and 30th minutes and at the 1st and 2nd hours. The subsequent pain evaluations were made by the parents at home, at the postoperative 6th, 12th, 18th and 24th hours. RESULTS: Seven patients were excluded from the study, and seventy eight patients were evaluated for analysis. Patients in PDB-Group had significantly lower postoperative pain intensity and lower mCHEOPS scores (3.83 ± 0.98) when compared to the PNB-Group (6.47 ± 0.91) (P < .01) at all measurement times and none of patients in PDB-Group had additional analgesic requirements up to 24 hours. Patients in the PNB-Group had significantly more analgesic requirements at all measurements times except at the 1st, 2nd, 24th hours. 3.8%, 30.8%, 46.2% and 59% of the patients in the PNB group needed additional analgesia respectively at 5th, 6th, 12th and 18th hours. CONCLUSION: Pudendal nerve block provided additional analgesic free period and had better analgesic efficiency compared to the penile nerve block lasting until 24 hours after operation.

The Assessment of Risk Factors for Difficult Intubation in Thyroid Patients.

OBJECTIVES: We aimed to assess possible risk factors related to difficult intubation in patients undergoing thyroid surgery. METHODS: We prospectively collected data of 200 patients scheduled for thyroid surgery. Clinical risk factors were defined as: Mallampati score, interincisor gap, thyromental distance, sternomental distance, range of neck motion, body mass index, neck circumference, goiter, the presence of radiological findings suggesting compression and thyroid weight. All evaluations were performed with Macintosh assessed for Cormack and Lehane (CL) classification and modified intubation difficulty scale (MIDS). RESULTS: It was observed that the proportion of patients with a thyroid weight ≥40 g, goiter, a Macintosh CL score = 3-4 and the mean neck circumference were significantly higher in the group with a MIDS score >5 (p = 0.018, p = 0.011, p < 0.001, respectively). CONCLUSION: The presence of a palpable goiter, thyroid weight ≥40 g and thyromental distance <6.5 cm were risk factors associated with difficult intubation in the multivariate regression model.

Edema laringotraqueal a causa de una lesión térmica: Complicación tras una tiroidectomía en niños / Laryngotracheal edema due to thermal injury: A complication after thyroidectomy in children

La insuficiencia respiratoria posoperatoria es una complicación grave de la tiroidectomia, y su origen puede ser multifactorial, especialmente en los niños. Presentamos el caso de dos hermanos sometidos a una tiroidectomia que luego tuvieron dificultad respiratoria. Para la disección de la tiroides se emplearon un bisturí armónico y el sistema de sellado vascular bipolar electrotérmico. Ambos pacientes presentaron problemas para respirar tempranamente en el posoperatorio. El hermano mayor tuvo dificultad respiratoria leve durante 24 horas, que se resolvió espontáneamente. Se extubó a la hermana menor, pero tuvo estridor grave acompañado de tiraje intercostal y retracción abdominal. Se la volvió a intubar y se la trasladó a la UCI, donde se la conectó a un respirador. Permaneció en la UCI durante 14 días debido a múltiples intentos fallidos de extubación. Es probable que los síntomas fueran más graves en la niña pequeña debido a que la pared de la tráquea era más blanda y los cartílagos, más débiles. Es necesario considerar las posibles complicaciones respiratorias posoperatorias a causa de una lesión térmica o una técnica quirúrgica inadecuada tras una tiroidectomía.

Postoperative respiratory insufficiency is a serious complication of total thyroidectomies which can be multifactorial, especially in children. We report two siblings who had undergone thyroidectomy with subsequent respiratory distress. Electrothermal bipolar and harmonic scalpel were used during thyroid dissections. Both patients had early postoperative respiratory problems. The older one suffered from mild respiratory distress for 24 hours and then he spontaneously recovered. The younger one was extubated but then she had serious stridor accompanied with abdominal and intercostal retractions. She was re-intubated and admitted to ICU for mechanical ventilatory support, where she stayed for 14 days due to multiple failed extubation attempts. The symptoms were more severe in the younger child probably due to softer tracheal wall and weaker tracheal cartilages. We should keep in mind the probable postoperative respiratory complications due to thermal injury or inappropriate surgical technique after thyroid surgeries.

Anaesthetic Management of a Child with a Massive Mediastinal Mass.

Mediastinal masses are benign or malignant tumours that originate from the thymus, thyroid, lung, lymphoid system, pleura, or pericardium. Cardiovascular and respiratory symptoms may occur because of the compression of surrounding tissues along with growing mass. In this study, we present the anaesthetic management of a 6-month-old child having a massive anterior mediastinal mass that had a compressing effect.

Transversus Abdominis Plane (TAP) block for postoperative analgesia in neonates and young infants: retrospective analysis of a case series. TAP blocks in neonates and young infants.

BACKGROUND: The effectiveness of the TAP block in children has been well characterized in literature. However, there are only few reports about TAP block in the neonates and low birth weight groups. This is a retrospective observational analysis of ultrasound - assisted TAP blocks in neonates and young infants. The aim of this study to analyze retrospectively the analgesic effectiveness of TAP block in neonates and infants undergoing abdominal and inguinal surgeries. METHODS: Thirty-four cases of neonates and infants with (whom) applied TAP block were retrospectively analyzed. The TAP block was performed postoperatively in supraumbilical surgeries and preoperatively in infraumbilical surgeries. The TAP block was applied with 0.8 ml/kg-1 of 0.25% bupivacaine in unilateral approach and 1.6 mlkg-1 of 0.125% bupivacaine in bilateral approach. The CRIES Pain Scale was used for postoperative pain measurement of neonates. RESULTS: The patient's age ranged from 2 to 88 day-old with a mean (SD) of 36.2(24.2). Eleven of them were premature babies. The weight ranged from 1.6 to 5.8 with a mean (SD) of 3.7kg (1.1). Twenty-nine patients were extubated at the end of the surgery and the other patients within 12 hours. 67.7% infants required no additional postoperative analgesic in 24 hours and none of them required narcotic analgesics. CONCLUSIONS: Our conclusion is that the use of TAP blocks results in low analgesic requirements and a low incidence of postoperative intubation and mechanical ventilation in neonates and infants. It should be considered in this age group of child for postoperative analgesia.

Pudendal Versus Caudal Block in Children Undergoing Hypospadias Surgery: A Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: Postoperative pain management after hypospadias surgery is often challenging. Caudal block is used for analgesia but has limitations. This study compares the analgesic efficiency of pudendal block with that of caudal block in pediatric patients undergoing hypospadias repair surgery. METHODS: This prospective, double-blind, randomized, controlled study enrolled 84 patients receiving pudendal block or caudal block before hypospadias surgery. In the pudendal group, the pudendal nerve was identified using a nerve stimulator, and the block consisted of 0.25% bupivacaine 0.5 mL/kg. In the caudal group, the caudal block used 0.2% bupivacaine 1 mL/kg. Our primary outcome was pain intensity within 24 hours postoperatively. The trial was registered at ClinicalTrials.gov (number: NCT02390388). RESULTS: For the primary outcome, patients in the pudendal group had lower postoperative pain intensity when compared with the caudal group (P < 0.001). Three patients in the pudendal group and all of the patients in the caudal group needed additional analgesia within 24 hours after the surgery (P < 0.001). The family satisfaction rate was significantly higher in the pudendal group (P < 0.001). CONCLUSIONS: For the pudendal group, the pain scores for the first 24 hours after the surgery were significantly lower and the duration of analgesia was longer.

Anafilaxia tras la administración de amikacina con metabisulfito de sodio a un recién nacido prematuro / Anaphylaxis after administration of amikacin containing sodium metabisulfite in a premature newborn

La anafilaxia es una reacción de hipersensibilidad sistemica y grave, de inicio rápido y potencialmente mortal. En los recién nacidos prematuros, el sistema inmunitario aún no ha madurado y, por lo tanto, tienen menos probabilidades de presentar anafilaxia. La administración de amikacina, que contenía metabisulfito de sodio, a un prematuro de 3 días de vida le indujo anafilaxia casi mortal. Debido a que se sospechaba un caso de anafilaxia, se inició la administración de amikacina en el bebé. Una vez comenzado el tratamiento, se observó una mejoría clínica. Al tercer día de tratamiento con amikacina, el recién nacido tuvo, repentinamente, taquipnea, taquicardia, angioedema y cianosis. Se le diagnosticó anafilaxia y se inició el tratamiento. Una hora después de la mejoría clínica, se produjo una reacción tardía. Inmediatamente, se intubó al recién nacido. La anafilaxia es una emergencia médica; por lo tanto, los médicos deben realizar una evaluación rápida y atenta para detectar esta reacción potencialmente mortal. Incluso después del tratamiento satisfactorio de la anafilaxia, el paciente debe permanecer bajo observación durante 72 horas dada la posibilidad de una reacción bifásica.

Anaphylaxis is a serious systemic hypersensitivity reaction that is rapid in onset and can cause death. Premature newborns, whose immunological system is immature, are less likely to develop anaphylaxis. Administration of amikacin, containing sodium metabisulfite, to a 3-day-old premature newborn, induced a near fatal anaphylaxis. After suspicion of sepsis, the baby was started on amikacin. Clinical improvement was observed after initiation of treatment. On the third day of treatment with amikacin, the newborn suddenly developed tachypnea, tachycardia, angioedema and cyanosis. Anaphylaxis was diagnosed and treated. Latent reaction occurred after one hour of clinical improvement. The baby was intubated immediately. Anaphylaxis is a medical emergency; therefore the clinicians should have a rapid and careful assessment about this potentially fatal reaction. Even after successful treatment of anaphylaxis, the patient should be under observation for 72 hours because of the possibility of a biphasic reaction.
