Laparoscopic-guided versus transincisional rectus sheath block for pediatric single-incision laparoscopic cholecystectomy: A randomized controlled trial.

PURPOSE: The purpose of our study was to compare the effectiveness of transincisional (TI) versus laparoscopic-guided (LG) rectus sheath block (RSB) for pain control following pediatric single-incision laparoscopic cholecystectomy (SILC). METHODS: Forty-eight patients 10-21 years old presenting to a single institution for SILC from 2015 to 2018 were randomized to TI or LG RSB. Apart from RSB technique, perioperative care protocols were identical between groups. Pain scores were assessed with validated measures upon arrival in the postanesthesia care unit (PACU) and at regular intervals until discharge. The patients and those assessing them were blinded to RSB technique. The primary outcome was pain score 60 min after PACU arrival. Secondary outcomes included pain scores throughout the PACU stay, opioids (reported as morphine milligram equivalents (MME) per kg bodyweight) administered in PACU, length of stay, outpatient pain scores and opioid use, and adverse events. Groups were compared on outcomes using t test and generalized estimating equations for continuous variables and Fisher's exact test for categorical variables with significance at α = 0.05. RESULTS: Mean age of the 48 subjects was 15 years (range = 11-20). The majority (79%) were female. Indications for surgery included symptomatic cholelithiasis (n = 41), acute cholecystitis (n = 4), gallstone pancreatitis (n = 2) and choledocholithiasis (n = 1). Mean (standard deviation) operative time was 61 (±23) min overall. No statistically significant differences in demographics, indication, operative time, or intraoperative analgesia were observed between TI (n = 24) and LG (n = 24) groups. The mean 60-min pain score was 3.4 (±2.6) in the LG group versus 3.8 (±2.1) in the TI group (p = 0.573). No significant differences were detected between groups in overall PACU or outpatient pain scores, PACU or outpatient opioid use, length of stay, or incidence of complications. Overall, mean opioid use was 0.1 MME/kg in the PACU and 0.5 MME/kg in the outpatient setting. Mean postoperative length of stay was 0.2 day. There were no major complications. CONCLUSION: Laparoscopic-guided rectus sheath block is not superior to transincisional rectus sheath block for pain control following pediatric single-incision laparoscopic cholecystectomy. The single-incision laparoscopic approach combined with rectus sheath block resulted in effective pain control, low opioid use, and expedited length of stay with no major complications. LEVEL OF EVIDENCE: Level I, treatment study, randomized controlled trial.

External caliper-based measurements of the modified percent depth as an alternative to cross-sectional imaging for assessing the severity of pectus excavatum.

BACKGROUND: Cross-sectional imaging (CSI) may be clinically unnecessary in the evaluation of pectus excavatum (PE). The purpose of our study was to prospectively evaluate the accuracy and reliability of the modified percent depth (MPD), derived from caliper-based external measurements, in identifying PE. METHODS: Children 11-21 years old presenting for evaluation of PE or to obtain thoracic cross-sectional imaging for other indications were measured to derive the Modified Percent Depth. The Haller Index (HI) and Correction Index (CI) were calculated from CSI. Receiver-Operator Characteristic (ROC) analysis was used to compare the sensitivity and specificity of MPD, HI, and CI. Interrater reliability was assessed using Spearman's correlation coefficient and Cohen's Kappa coefficient. RESULTS: Of 199 patients, 76 (38%) had severe PE. Median age was 16 years (range = 11-21). The median Modified Percent Depth was 21.4% (IQR = 16.2-26.3) among those with PE versus 4.1% (IQR = 1.7-6.4) in those without (p < 0.001). MPD ≥ 11% exhibited similar sensitivity and specificity to HI ≥ 3.25 and CI ≥ 10 for identifying PE (ROC 0.98 vs. 0.97 vs. 0.98, respectively, p = 0.41). With respect to interrater reliability, independent clinicians' caliper measurements exhibited 87% agreement when identifying MPD ≥ 11% (p < 0.001) with excellent correlation (Spearman's ρ > 0.71, p < 0.001). CONCLUSION: Caliper-based, physical examination measurements of the Modified Percent Depth reliably identify pectus excavatum and represent an alternative to CSI-based measurements for the assessment of PE. TYPE OF STUDY: Diagnostic test. LEVEL OF EVIDENCE: Level II.

Quality Initiative Using Theory of Change and Visual Analytics to Improve Controlled Substance Documentation Discrepancies in the Operating Room.

BACKGROUND: Discrepancies in controlled substance documentation are common and can lead to legal and regulatory repercussions. We introduced a visual analytics dashboard to assist in a quality improvement project to reduce the discrepancies in controlled substance documentation in the operating room (OR) of our free-standing pediatric hospital. METHODS: Visual analytics were applied to collected documentation discrepancy audit data and were used to track progress of the project, to motivate the OR team, and in analyzing where further improvements could be made. This was part of a seven-step improvement plan based on the Theory of Change with a logic model framework approach. RESULTS: The introduction of the visual analytics dashboard contributed a 24% improvement in controlled substance documentation discrepancy. The project overall reduced documentation errors by 71% over the studied period. CONCLUSION: We used visual analytics to simultaneously analyze, monitor, and interpret vast amounts of data and present them in an appealing format. In conjunction with quality-improvement principles, this led to a significant improvement in controlled substance documentation discrepancies.
