Filter by:Hypospadias, seen in every 200-300 births, is one of the most common congenital anomalies of the penis and is defined as the urethral meatus being located in the ventral part of the penis instead of its normal place. The surgery of this anomaly is very painful in the postoperative period and requires long-term analgesia. Regional anesthesia methods combined with general anesthesia play an important role in providing effective and long-term postoperative pain control in pediatric penile surgery. These methods also reduce postoperative morbidity, enable early mobilization and significantly decrease the need for narcotic analgesics. The investigator's hypothesis is peripheral nerve blocks are superior to neuraxial blocks as the blocks provide longer-term analgesia and have fewer side effects.
This study aims to determine if intravenous Dexamethasone combined with a pudendal nerve block is able to prolong postoperative analgesia in children undergoing hypospadias repair.
The aim of this study is to compare prepuce tissue samples from healthy male children who applied for circumcision and children with isolated hypospadias. Estrogen receptor 1 (ER1), androgen receptor (AR), FGFR2, transforming growth factor beta (TGF beta) and HOXA13 gene expression in the prepuce is planned to investigate via polymerase chain reaction (PCR) method. Mucosal vascular and nerve densities, and extracellular matrix density of laminin and collagen protein is planned to investigate via immunohistochemical examination.
The study is designed to explore any association between the caudal epidural block(CEB) given for perioperative analgesia and the occurrence of urethrocutaneous fistula postoperatively in children undergoing distal hypospadias repair .We also intend to study the duration of penile engorgement due to CEB causing penile oedema which may subsequently play a role in fistula formation. The pilot study will recruit children under 8 years of age diagnosed with distal hypospadias scheduled to undergo Tubularised Incised Plate Urethroplasty, operated by a single paediatric surgeon. General anaesthesia will be induced with sevoflurane in oxygen nitrous oxide mixture supplemented by fentanyl citrate and atracurium besylate in all children. LMA Pro SealTMof appropriate size will be inserted. Children in group I will then be given caudal epidural block (CEB) as per our practice protocol. Children in group II will be given additional intravenous fentanyl citrate. All children will be followed postoperatively till 3 months to evaluate incidence of urethtocutaneous fistula. The prospective study attempts to eliminate previously reported confounding factors.
Dexmedetomidine (DEXM) is a highly selective α2-adrenoceptor agonist that has been used increasingly in pediatric anesthesia. This prospective double blinded randomized comparative study is designed to evaluate the analgesic effect of caudal increasing doses of DEXM 0.5 , 1 , 1.5 , 2µg/kg combined with Levobupivacaine (Levob) 0.125% (ED95% =125%=least effective concentration) in providing pain relief over a 24-h period and lowest surgical stress peak. Study hypothesis: Levobupivacaine 0.125 %( ED95) combined with different increasing doses of dexamedatomedine >1 µg/kg could not add more analgesic & stress response obtundation outcome, but increase side effects (sedation and hemodynamic depression). The peak cortisol level during urology surgery was at the end of the 1st postoperative (PO) hour. Aim of the Study: To detect the optimal analgesic and safe caudal adjuvant DEXM dose associated with the least side effects& stress response modulation, guided by PO Cortisol peak difference in between the study groups during pediatric hypospadias surgery.
The purpose of this study is to determine whether dietary cholic acid therapy benefits people with Smith-Lemli-Opitz syndrome (SLOS) by leading to an increase in plasma cholesterol and reduction in harmful cholesterol precursors. SLOS participants will be treated with dietary cholic acid for 8 weeks and plasma cholesterol and cholesterol precursor metabolites will be measured.
The proposed study will assess whether an interactive perioperative teaching platform (IPTP) provided to families of patients undergoing ambulatory pediatric surgery will reduce families' anxiety, and improve satisfaction and understanding, relative to current practice. The IPTP will educate patient families on the continuum of their child's surgical experience, from arriving at the hospital through registration, the operating room (OR), and the hospital floor. An active video format will be used to provide instructions for navigating the hospital; describe induction of anesthesia and the surgical procedure; and provide post-surgery and post-discharge instructions for pain management. A comparison cohort of patients undergoing surgery without access to the IPTP will be recruited to assess the benefits of the IPTP for improving metrics of family satisfaction, preoperative anxiety, and postoperative understanding of discharge instructions.
Opioids are an important component of post-operative pain management among children, but are often prescribed in excess and rarely disposed of appropriately. The lack of prompt and proper opioid disposal after recovery from surgery is contributing to the opioid crisis in Ohio by placing children at risk of accidental ingestion of opioids remaining in the home and allowing for unused opioids to be diverted for non-medical use. The investigators propose to reduce the burden of the opioid crisis in Ohio by testing a strategy to increase proper opioid disposal by families of children undergoing outpatient surgery. The investigators will test the impact of a novel opioid disposal mechanism, the Deterra® drug deactivation system, after pediatric surgical operations. This system deactivates pills, liquids, or patches, allowing for their disposal in the home garbage. The investigators propose to evaluate the effectiveness of providing Deterra® bags to families of children having surgery on their disposal of excess opioids. The investigators will perform a randomized controlled trial (RCT) to test the effectiveness of Deterra® to improve opioid disposal among families of children having outpatient surgery at Nationwide Children's Hospital.
Pain after hypospadias surgery is a challenging issue to solve for anesthesists. Many different analgesia techniques were defined in literature for this purpose. The investigators have implemented application of ultrasound guided dorsal penile nerve block into practice for these type of surgeries. Main purpose of this study is to compare the efficacy of nerve stimulator guided pudendal nerve block with ultrasound guided dorsal penile nerve block for postoperative analgesia after hypospadias surgery.
Hypospadias is a common condition where the opening of the penis is not located at the tip, but along the underside of the penis. It is estimated to occur in 1/300 live male births, making it one of the most common birth defects. Degrees of hypospadias ranged from minor to severe depending on the location of the opening. Surgical repair is often required and involves placement of a catheter for the urine to drain with known urinary colonization found on prior retrospective studies. The current practice of using preventative antibiotics as long as the catheter is in place is conflicting with resent studies that show antibiotics may not be necessary to prevent urinary tract infections (UTIs). The purpose of this study was to see how common symptomatic UTIs were after hypospadias repair surgery; and to see whether routine antibiotic use after surgery affected the rate of UTIs. Subjects were randomized to either receive antibiotics or no antibiotics after distal hypospadias repair. The research coordinator made follow-up phone calls with the family and the primary care provider (PCP) after stent removal, 30 days post surgery and after the 3 month post surgical visit.
