Ultrasonographic assessment of metoclopramide effect on gastric volume in parturients females undergoing Caesarean section: a randomized double blind study.

BACKGROUND: The prokinetic effect of metoclopramide promotes gastric emptying and decreases stomach capacity. The aim of the present study was to assess the efficacy of metoclopramide in reducing gastric contents and volume using gastric point-of-care ultrasonography (PoCUS) in parturients females prepared for elective Cesarean section under general anesthesia. METHODS: A total of 111 parturient females were randomly allocated to one of two groups. The intervention group (Group M; N.=56) received 10 mg metoclopramide diluted in 10 mL 0.9% normal saline. The control group (Group C; N.=55): received 10 mL 0.9% normal saline. The cross-sectional area and volume of stomach contents were measured using ultrasound before and one hour after the administration of metoclopramide or saline. RESULTS: Statistically significant differences in mean antral cross-sectional area and gastric volume were observed between the two groups (P<0.001). Group M had significantly lower rates of nausea and vomiting compared to the control group. CONCLUSIONS: Metoclopramide decreases gastric volume, reduces postoperative nausea and vomiting, and may lower the risk of aspiration when used as premedication before obstetric surgery. Preoperative gastric PoCUS has utility in objectively assessing stomach volume and contents.

A multidisciplinary intervention to reduce central line-associated bloodstream infection in pediatrics and neonatal intensive care units.

BACKGROUND: To date, central line-associated bloodstream infections (CLABSIs) are the most common healthcare-associated infections in high-risk neonates and children. These infections are associated with significantly longer hospital stays, increased health care cost, and mortality in the health care systems. Application of evidence-based preventive interventions has proven to decrease CLABSI rate. The purpose of this study is to reduce the undesired relative high CLABSI rate through the adoption of standardized quality improvement interventions. METHODS: and Methods: The study employed a pre-post-intervention design. Phase one is a retrospective calculation of 12 months of surveillance period as a baseline. Phase 2 establishes a multidisciplinary quality improvement intervention, which includes the formation of a dedicated central line insertion team, provision of central line kit at the bedside, training and educating the team, and selecting bundle checklist. In the third phase, we performed auditing and calculating the checklist compliance and monthly feedback for 12 consecutive post-intervention months. During phase 1 and 3, we calculated the following measures; CLABSI per 1000 catheter-days, duration of central line use, and device utilization ratio. RESULTS: During the post-intervention phase the CLABSI rate significantly reduced by 59.5% from 7.5 to 3.0 per 1000 central line day, and the duration of use of the central line decreased from 21.3 ± 9.9 to 11.0 ± 3.2 days (P < 0.05). CONCLUSION: Implementation of quality improvement multidisciplinary intervention; central line insertion and maintenance care bundle, dedicated IV team, education and feedback effectively reduced the rate of CLABSI within our pediatrics and neonatal ICUs.

Dexmedetomidine versus clonidine adjuvants to levobupivacaine for ultrasound-guided transversus abdominis plane block in paediatric laparoscopic orchiopexy: Randomized, double-blind study.

BACKGROUND: Laparoscopic surgeries are associated with less postoperative pain and adverse events compared to open procedures. But, it still reduces the quality of life in children. Transversus abdominis plane (TAP) block is used to reduce pain. We hypothesized that dexmedetomidine or clonidine could improve the analgesic profile of levobupivacaine to the same extent during TAP block in children. METHODS: Ninety children were randomly allocated in a randomized double-blind trial to receive bilateral TAP block with levobupivacaine plus normal saline (group B, n = 30), or dexmedetomidine (group D, n = 30) or clonidine (group C, n = 30). Primary outcome was the modified Children's Hospital of Eastern Ontario Pain Scale score. Secondary outcomes included time to initial analgesic request, number of analgesic claims, total analgesic consumption, parents' satisfaction, sedation score and complications. RESULTS: Children of group D showed reduced pain scores compared to other groups. They represented the longest period of analgesia (565.00 ± 71.5 min) with p < 0.001, and fewer patients required two doses of analgesia during the first postoperative day. The cumulative amount of backup analgesia was significantly different between these groups (p = 0.026). Higher parents' satisfaction scores were recorded in groups D and C compared to group B. Sedation among the study groups revealed significant differences (p = 0.035), but no severe complications were recorded. CONCLUSIONS: Adding dexmedetomidine to levobupivacaine can extend the time of analgesia and reduce the use of postoperative backup analgesics with minimal sedation effects when used in TAP block in paediatrics undergoing laparoscopic orchiopexy. Clonidine can be used as an alternative adjuvant to local anaesthetics with good postoperative analgesic profiles. SIGNIFICANCE: Clonidine can alternate dexmedetomidine during TAP block with local anesthetics for pediatrics laparoscopies. Both can lead to better postoperative analgesic profiles. Clonidine may be preferred, especially in our developing regions, because of its easy availability and lower cost than that of dexmedetomidine.

Topical use of tranexamic acid versus epinephrine to optimise surgical field during exploratory tympanotomy.

OBJECTIVE: To explore the effect of diluting tranexamic acid as 1000 mg versus epinephrine as 1 mg in a volume of 200 mL of normal saline used for local washing and rinsing of the used gauze at the surgical bleeding sites during microscopic ear surgeries. METHODS: In a randomised, double-blind trial, sixty patients scheduled for elective microscopic exploratory tympanotomy consented to participate after meeting the inclusion criteria. Patients assigned using the balanced block randomisation method into two similar groups; one received tranexamic acid (TXA), and the other received epinephrine. The outcome of the study focused on blood pressure, heart rate, quality of surgical field assessed via Boezaart score, the volume of bleeding, and the incidence of complications. RESULTS: The more prominent findings were the statistically significant and favourable surgical field assessment according to the Boezaart score, and lower estimates of bleeding demonstrated in the TXA group compared to the epinephrine group, along the time of the study P-value was < 0.05. The haemodynamic monitoring showed promising changes in the TXA group compared with the epinephrine group in terms of lower mean blood pressure and lower heart rate that reached the level of statistical significance during the time of the study. CONCLUSION: the use of topical tranexamic acid during microscopic ear surgeries is associated with a better surgical field, less bleeding, and favourable haemodynamic parameters compared to epinephrine.
