NCT ID: NCT05205473 Not yet recruiting - Nerve Block Clinical Trials

Sciatic Nerve Blockade by Subgluteal Access 12.5 ml of 1% Lidocaine: US Guidance Versus US Guidance With Electrical Stimulation of Peripheral Nerves (Influence of the Sciatic Nerve Blockade on the Effectiveness of Small Doses of Local Anesthetic.).

EPBwEPN
Start date: February 2022
Phase: N/A
Study type: Interventional

In modern anesthesiology, peripheral nerve blocks are performed using ultrasound control and electrical stimulation of peripheral nerves (PEN), or only ultrasound control or only EPN. The most effective methods are with the use of ultrasound control. Until now, the effectiveness of the sciatic nerve blockade by the subgluteal approach, performed only under ultrasound control without EPN, in comparison with the blockade of the sciatic nerve performed under ultrasound control with EPN, has not been established. There is no data on how the effectiveness of the blockade of the sciatic nerve with small doses of lidocaine is influenced by the method of performing the blockade: under ultrasound control versus ultrasound control with electrostimulation of the nerve. Research hypothesis: the blockade of the sciatic nerve by the subgluteal approach (12.5 ml 1%lidocaine -Minimum Effective Dose - previously established ) performed only under ultrasound control has the same effectiveness as the blockade performed under the ultrasound control with EPN.

NCT ID: NCT05184465 Completed - Anesthesia, Spinal Clinical Trials

Comparison of the Efficacy of 0.5% Bupivacaine, 0.5% Levobupivacaine, and 0.5% Hyperbaric Bupivacaine

BvsLBvsHB
Start date: December 18, 2017
Phase: N/A
Study type: Interventional

About 15 million spinal anesthesia procedures are performed worldwide each year. In the daily practice of the anesthesiologist for intrathecal use there are various local anesthetics such as bupivacaine, hyperbaric solution of bupivacaine, ropivacaine and levobupivacaine. From 1946 to 2017, only 16 studies comparing the clinical efficacy of isobaric and hyperbaric bupivacaine in nonpregnant patients have been conducted according to various databases. The small sample size and high heterogeneity of these results suggest that all results should be treated with caution. And, there is no conclusive evidence in favor of isobaric or hyperbaric bupivacaine regarding efficacy or side effects in the general surgical population. The literature describes such advantages of levobupivacaine as less cardiotoxicity, longer period of analgesia, more pronounced activity against sensory fibers than against motor fibers. In some studies it has been shown that levobupivacaine is equal to isobaric bupivacaine in efficacy. The efficacy of hyperbaric levobupivacaine equivalent to hyperbaric bupivacaine when administered intrathecally has also been shown on volunteers. However, in the literature there are different data on clinical efficacy of levobupivakin in comparison with ropivacaine and levobupivacaine. So during operations on extremities out of 20 patients surgical anesthesia developed in 18 patients. Fattorini F. et al. D in their study stated the same effectiveness of bupivacaine and levobupivacaine, but when using levobupivacaine in one patient general anesthesia was used due to insufficient spinal anesthesia. Other studies also reported similar efficacy of the two drugs, but surgical satisfaction with intraoperative anesthesia was 92.9% for bupivacaine and 83.9% for levobupivacaine for knee arthoroscopy. In their study, P Gautier et al. noted significantly lower efficacy of levobupivacaine in caesarean section compared to bupivacaine and ropivacaine for intrathecal use: 80% vs. 90% and 87%, respectively. According to Heng Sia et al. there is no clear evidence of the advantage of hyperbaric bupivacaine over isobaric bupivacaine for spinal anesthesia for cesarean section. The authors also noted that adequate randomized clinical trials with clear definitions, criteria and methodology for evaluating the transition to general anesthesia, requirements for additional analgesia, nausea, vomiting and sensory testing are needed. There is no clear practical guide to help anesthesiologists make informed decisions about the use of some form of intrathecal bupivacaine in non-cesarean surgery. Carefully designed, adequately conducted studies can provide further results that will contribute to sound clinical decision making. Given the above, the aim of the study is to compare the effectiveness of spinal anesthesia (SA) performed with 0.5% isobaric bupivacaine solution, 0.5% levobupivacaine solution and 0.5% hyperbaric bupivacaine solution in equivalent volumes in lower limb surgeries.

NCT ID: NCT05062044 Recruiting - Clinical trials for Prevention of Vitamin Deficiency During and/or Before Pregnancy

A Study to Gather Information About the Progress and Outcomes of Pregnancy in Women Using Various Vitamin Support Plans Before and During Pregnancy

Start date: December 2, 2021
Phase:
Study type: Observational

This is an observational study in which data from the participants who will be taking different vitamin supplementation regimes before and during pregnancy. Vitamin deficiency is a condition where there is not enough vitamins in the body. During pregnancy, a woman's body may require more vitamins than usual. When the body does not get enough vitamins, people can take vitamin supplements to help increase the amount of vitamins in the body. It is already known, that polyvitamins can decrease risks of anemia (low level of red cells in the blood), neural tube defects (severe congenital anomaly of neural system) or other malformations, but also on several pregnancy complications. Nevertheless, a significant amount of evidence on the use of vitamins during pregnancy has been obtained in countries with low and middle level of living standards. Countries with higher living standards may have different prevalence of vitamin insufficiency, thereby it is not clearly known how vitamin supplementation may help to reduce pregnancy complications in these population. So, researchers think it is important to do more studies. Elevit contains many different vitamins and minerals. These vitamins and minerals are important to help women before and during pregnancy. In this study, the researchers want to collect more data about how well pregnancies progress and the outcomes of the pregnancies in women who are taking different vitamin treatment or supplements, including elevit. To do this, the researchers will review information collected from the participants to: - calculate how many women give birth without any complications between weeks 37 and 42 of their pregnancies - calculate how many women have low levels of red blood cells in the blood during the third trimester of their pregnancies - calculate how many women have a serious condition called preeclampsia during their pregnancy, a condition in which pregnant women have a sudden rise in blood pressure and swelling in the hands, feet and face - calculate how many women give birth to babies who weigh less than expected at the time of their birth - give the women a questionnaire to complete during each trimester to see how they are feeling The participants will have decided with their doctor to start their vitamin treatment or supplements before getting pregnant or during their pregnancy. During the study, the researchers will collect the women's information from their medical records taken during their regular medical appointments. The study will include women who are pregnant and who are planning to get pregnant. The study will include both women who have vitamin deficiency and women who do not have vitamin deficiency. Each participant will be in this study for up to 18 months., The whole study will last about 2 years and 10 months. During this time, the participants will visit their doctor 5 times as part of their usual care. The study is planned to collect data from October 2021 until June 2024.
