A retrospective study of multimodal analgesic treatment after laparoscopic appendectomy in children.

BACKGROUND: Laparoscopic appendectomy is a common emergency pediatric surgery procedure accompanied by substantial pain (pain scores >4 for >60% of the time) in 33% of these patients. We introduced a bundle of pain management interventions including local anesthetic infiltration at the incision site, intravenous (IV) opioids by patient-controlled analgesia (PCA), and scheduled doses of IV ketorolac and oral acetaminophen/hydrocodone. OBJECTIVES: To evaluate the effect of these pain management interventions on pain control after laparoscopic appendectomy. METHODS: We retrospectively studied pain in 206 children above 7 years of age undergoing laparoscopic appendectomy from December 2011 to February 2012 at our institution. We extracted data on patient demographics, duration of anesthesia and surgery, intraoperative opioids, local anesthetic infiltration, surgical procedure reports, along with pain scores, postoperative PCA use, and opioid-related complications and hospital stays. Patients were divided into two groups - simple appendicitis without peritonitis and appendicitis with generalized peritonitis. RESULTS: The incidence of substantial pain when the multimodal regimen was used was 12%, which is significantly lower than earlier reports (Fisher's exact test P < 0.001). Patients with generalized peritonitis experienced more pain, consumed more opioids, had more unmet PCA demands, and a higher incidence of respiratory depression compared with those with simple appendicitis. CONCLUSION: The multimodal regimen of local anesthetic infiltration, opioid by PCA, NSAIDs, and oral acetaminophen/hydrocodone reduced the incidence of substantial pain. Additional studies are required to identify subgroups of patients with minimal opioid requirements who can benefit from modifications of this regimen.

Outcomes of Non-anesthesiologist-Administered Propofol in Pediatric Gastroenterology Procedures.

Background and Aims: Non-anesthesiologist-administered propofol (NAAP) has been found to have an acceptable safety profile in adult endoscopy, but its use remains controversial and pediatric data is limited. Our aim was to examine the safety and efficacy of NAAP provided by pediatric hospitalists in pediatric endoscopy. Methods: We retrospectively reviewed 929 esophagogastroduodenoscopy (EGD), colonoscopy, and combined EGD/colonoscopy cases in children aged 5-20 years between April 2015 and December 2016 at a large children's hospital. We analyzed the data for adverse events in relation to demographics and anthropometrics, American Society of Anesthesiologists physical classification score, presence of a trainee, comorbid conditions, and procedure time. Results: A total of 929 cases were included of which 496 (53%) were completed with NAAP. Seventeen (3.4%) of NAAP cases had an adverse event including the following: 12 cases of hypoxia, 2 cardiac, and 3 gastrointestinal adverse events. General anesthesia cases had 62 (14.3%) adverse events including the following: 54 cases of hypoxia, 1 cardiac, 7 gastrointestinal, and 1 urologic adverse event. No adverse events in either group required major resuscitation. NAAP vs. general anesthesia had a lower overall adverse event rate (3.4 vs. 14.3%, p < 0.0004) and respiratory adverse event rate (2.4% vs. 12.5%, p < 0.0004). Overall, cardiac and gastrointestinal adverse event rates between the two groups were comparable. When accounting for all captured factors via logistic regression, both younger age (P < 0.001) and general anesthesia (P < 0.0001) remained risk factors for an adverse event. Conclusion: The overall adverse event rate of NAAP was low (3.4%) with none requiring major resuscitation or hospitalization. This is comparable to studies of NAAP in adult endoscopy and suggests that NAAP provided by pediatric hospitalists has an acceptable safety profile.

Volumetric analysis of bone substitute material performance within the human sinus cavity of former head and neck cancer patients: A prospective, randomized clinical trial.

BACKGROUND: In numerous animal and human studies, it could be detected that in bone augmentation procedures, material's physicochemical characteristics can influence the cellular inflammatory pattern and therefore the integration in the host tissue. Histological, histomorphometrical, and clinical analyses of the integration of the biomaterial in the surrounding tissue are well established methodologies; however, they do not make a statement on volume and density changes of the augmented biomaterial. AIMS: The aim of the present study was to assess the volume and density of a xenogeneic (Bio-Oss®, BO) and a synthetic (NanoBone®, NB) bone substitute material in split-mouth sinus augmentations in former tumor patients to complete histological and histomorphometrical assessment. METHODS: Immediately and 6 months after sinus augmentation computed tomography scans were recorded, bone grafts were marked, and the volume was calculated with radiologic RIS-PACS software (General Electric Healthcare, Chalfont St. Giles, Great Britain) to determine the integration and degradation behavior of both biomaterials. RESULTS: Radiographic analysis revealed a volume reduction of the initial augmented bone substitute material (i.e. 100%) to 77.36 (±11.68) % in the BO-group, respectively, 75.82 (±22.28) % in the NB-group six months after augmentation. In both materials, the volume reduction was not significant. Bone density significantly increased in both groups. CONCLUSION: The presented radiological investigation presents a favorable method to obtain clinically relevant information concerning the integration and degradation behavior of bone substitute materials.
