RESUMO

OBJECTIVE: To identify associations between procedural characteristics and success of neonatal tracheal intubation (NTI) using video laryngoscopy (VL). DESIGN: Prospective single-centre observational study. SETTING: Quaternary neonatal intensive care unit. PATIENTS: Infants requiring NTI at the Children's Hospital of Philadelphia. INTERVENTIONS: VL NTI recordings were evaluated to assess 11 observable procedural characteristics hypothesised to be associated with VL NTI success. These characteristics included measures of procedural time and performance, glottic exposure and position, and laryngoscope blade tip location. MAIN OUTCOME MEASURE: VL NTI attempt success. RESULTS: A total of 109 patients underwent 109 intubation encounters with 164 intubation attempts. The first attempt success rate was 65%, and the overall encounter success rate was 100%. Successful VL NTI attempts were associated with shorter procedural duration (36 s vs 60 s, p<0.001) and improved Cormack-Lehane grade (63% grade I vs 49% grade II, p<0.001) compared with unsuccessful NTIs. Other factors more common in successful NTI attempts than unsuccessful attempts were laryngoscope blade placement to lift the epiglottis (45% vs 29%, p=0.002), fewer tracheal tube manoeuvres (3 vs 8, p<0.001) and a left-sided or non-visualised tongue location (76% vs 56%, p=0.009). CONCLUSION: We identified procedural characteristics visible on the VL screen that are associated with NTI procedural success. Study results may improve how VL is used to teach and perform neonatal intubation.

RESUMO

OBJECTIVE: To examine first attempt success and overall success of real-time ultrasound guided peripheral arterial cannulation in infants. STUDY DESIGN: Retrospective review of 477 ultrasound guided peripheral arterial cannulations in infants less than 1 year of age. Procedural and patient characteristics were evaluated to better understand factors related to procedural success. RESULTS: Ultrasound guided peripheral arterial cannulation had a first attempt success rate of 65% and an overall success rate of 86%. Success rates significantly differed by arterial location (p < 0.001). First attempt success and overall success were highest in the radial artery (72%, 91%) and lowest in the posterior tibial artery (44%, 71%). Success was more likely with greater age and greater weight (p = 0.006, p = 0.002). CONCLUSION: Success rates are high when using a real-time ultrasound-guided technique for peripheral arterial cannulation in infants. An infant's weight and selected artery are strong predictors of success when performing peripheral arterial cannulation. The use of procedural ultrasound may reduce unnecessary attempts and minimize procedure-related harm.

RESUMO

OBJECTIVE: Electrolyte, hemoglobin, and bilirubin values are routinely reported with point-of-care (POC) testing for blood gases. Results are rapidly available and require a small blood volume. Yet, these results are underutilized due to noted discrepancies between central laboratory (CL) and POC testing. The study aimed to determine the correlation between POC and CL measurement of electrolytes, hemoglobin, and bilirubin in neonates. STUDY DESIGN: Electrolyte, hemoglobin, and bilirubin results obtained from capillary blood over a 4-month period were analyzed. Each CL value was matched with a POC value from the same sample or another sample less than 1-hour apart. Agreement was determined by measuring the mean difference (MD) between paired samples with 95% limits of agreement (LOA) and Lin's concordance correlation (LCC). RESULTS: There were 355-paired sodium/potassium, 139 paired hemoglobin, and 197 paired bilirubin values analyzed. POC sodium values were lower (133.5 ± 5.8 mmol/L) than CL (140.2 ± 5.8 mmol/L), p <0.00001 with poor agreement (LCC = 0.49; MD = 6.7; 95% LOA: -13.6 to 0.14). POC potassium values were lower (4.6 ± 0.98 mmol/L) than CL (4.98 ± 1.24mEq/L), p < 0.0001, but with better concordance and agreement. (LCC = 0.6; MD = 0.4; 95% LOA: -2.3 to 1.4). There were no differences in hemoglobin between POC (14.3 ± 3.2 g/dL) and CL (14.4 ± 3.1 g/dL), p = 0.2 with good LCC (0.93) and in bilirubin values between POC (6.0 ± 3.2 mg/dL) and CL (5.8 ± 3.0 mg/dL), MD = 0.18, and p = 0.07. CONCLUSION: POC Sodium values are lower than CL. POC potassium levels are also lower, but the differences may not be clinically important while hemoglobin and bilirubin levels are similar between POC and CL. As POC potassium, hemoglobin, and bilirubin levels closely reflect CL values, these results can be relied upon to make clinical judgments in neonates. KEY POINTS: · Electrolyte, hemoglobin, and bilirubin are available as POC.. · POC sodium and potassium values are lower than CL results.. · Hemoglobin and bilirubin values are similar between POC and CL..

RESUMO

OBJECTIVES: Transplant nephrectomy is a technically challenging procedure with high complication rates. Morbidity and mortality are mostly due to hemorrhage or infection and are reported to be 17-60% and 1-39%, respectively. The most common surgical technique for transplant nephrectomy is sub-capsular, extraperitoneal approach which may result in fluid accumulation and subsequent super-infection. We report that intraperitoneal approach, after assuring hemostasis of the transplant pedicle, allows for passive drainage, decreases hematoma formation and minimizes the subsequent infection risk in the nephrectomy bed. MATERIAL AND METHODS: From July 2009 to July 2014 a total of 38 transplant nephrectomies were performed using the intraperitoneal window technique at Georgetown University MedStar Transplant Institute (MGTI). Data was collected retrospectively. RESULTS: Average age at the time of transplant nephrectomy was 43.9 ± 14.3, and the majority were male (55.3%). Mean time to nephrectomy was 71.7 ± 67.4 months following transplantation. Indications for nephrectomy included pain, hematuria, fever, and recalcitrant rejection. Average operative time was 97.1 ± 28.9 minutes, average blood loss was 172.5 ± 213.6 mL. A total of 9 (24%) complications occurred. Postoperative blood transfusion was the most common complication (15.7%) followed by 2 (5.3%) re-interventions; one take back for hematoma and one percutaneous drain placement for symptomatic fluid collection. We had no infection, postoperative sepsis, ICU admissions, or mortality. CONCLUSION: Transplant nephrectomy with peritoneal window is a technique with better results compared to the literature. An opening between the transplant cavity and the peritoneum allows for passive drainage of fluid and minimizes the risk of hematoma and abscess formation. This approach does not add significant time to the operation, furthermore it may decrease morbidity and mortality by reducing overall complications, namely hematoma formation and infection, which overall decreases rates of re-interventions and length of hospital stay.
