Hyoscine Butyl-bromide Versus Ondansetron for Nausea and Vomiting During Cesarean Section Under Spinal Anesthesia

overall incidence of intraoperative nausea and vomiting(IONV) during regional anesthesia for cesarean section is extremely variable, up to 80 percent , depending on the anesthetic technique used (spinal, epidural or combined spinal-epidural) and on the preventive and therapeutic measures taken.1 Spinal anesthesia for CS is safe and effective; it is currently the anesthetic technique of choice for elective Cesarean delivery (CD). However, maternal hypotension associated with spinal anesthesia is one of the primary causes of intraoperative nausea and/or vomiting (IONV); this symptom is thought to be caused by cerebral and gut hypoperfusion that stimulate the vomiting centre in the brainstem and cause serotonin release, respectively.2, 3 While bolus dosing of phenylephrine effectively treats maternal hypotension, it does not prevent intraoperative maternal nausea, which may be associated with established hypotension, and this may adversely affect patient satisfaction.4, 5 However, the unopposed vagal activity that occurs with sympathetic block might be another cause of intraoperative nausea and vomiting during spinal anesthesia.6 Both scopolamine and atropine are tertiary amines, which cross the blood-brain barrier with central side effects, such as confusion, sedation, or paradoxical excitation. However, Hyoscine butyl bromide (HBB) has a quaternary ammonium structure that does not cross through the blood-brain barrier and also with lower placental transfer than atropine, making it more suitable for use in pregnancy 7, 8. Hyoscine Butyl-bromide, also known as scopolamine butyl-bromide and sold under the brand name Buscopan.9 Despite being a quaternary ammonium compound, HBB is still capable of targeting the chemoreceptor trigger zone due to the lack of a well-developed blood-brain-barrier in the medulla oblongata, which potentiates the antiemetic effects that it produces through local action on the smooth muscle of the gastrointestinal tract.10 So, the aim of the current study is to examine the effect of prophylactic use of HBB and Ondansetron to decrease the incidence of intraoperative bradycardia and thus intraoperative nausea and vomiting in parturients undergoing CD under spinal anaesthesia.

The Effects of Inhaled Aromatherapy on Chemotherapy Induced Nausea (CINV) and Vomiting

This study is a three group, randomized, double blind, placebo-controlled trial with two repeated measurements. The same measurements will be collected for each participant during two consecutive chemotherapy treatment cycles.Subjects will be provided with written instructions as an educational handout as well as essential oil safety information. Subjects will be able to demonstrate an ability and accurate understanding of the proper use of the diffusers, using a demonstration diffuser, at the time of consent. At the time the subject will provide written informed consent, they will be randomly assigned to one of the three groups with a pocket diffuser containing either ginger essential oil, peppermint essential oil, or vanilla extract )placebo- control). This is based on a pre-determined list of random assignments. Each subject will be instructed to inhale from the pocket diffuser beginning on the day of their chemotherapy (Day 1) and continue using the inhaler for the next three consecutive days (Day 1-Day 4). The subjects will remove the cover of the pocket diffuser, place the pocket diffuser approximately an inch away from their nose and inhale three times with deep breathing (i.e., three sniffs). Subjects will take 3 sniffs of the aromatherapy inhaler three times daily (morning, afternoon, and evening). In addition to the Pre-treatment Assessment, occurring before each of the 2 cycles of chemotherapy, the subjects will be contacted to complete assessments at approximately 24 and 72 hours post-chemotherapy. A member of the study team will call the participant again at their preferred time of day to ask the survey questions. The same procedures will be repeated during the participant's second cycle of chemotherapy, which is likely two or three weeks after the first one.

Auriculotherapy and Acupuncture's Treatment for Chemotherapy-induced Nausea and Vomiting (CINV)

The management of chemotherapy-induced nausea and vomiting (CINV) has evolved in recent years and became less frequent. CINV include early (occurring within 24 hours of chemotherapy administration) and delayed (occurring within 4 days after chemotherapy) nausea and vomiting. Preventive treatment, such as Glucocorticoids, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists and neurokinin 1 (NK1) receptor antagonists, are administered according to the classification in 4 grades of expected CINV Very low: <10% occurrence of CINV; Low: 10 to 30% occurrence of CINV; Average: 30 to 90% occurrence of CINV; High: > 90% occurrence of CINV. These treatments have been the subject of recommendations. Despite these available treatments, some patients still complain of vomiting, or more frequently nausea and loss of appetite. Meanwhile, Chinese acupuncture has proven effective on the prevention of CINV as complementary treatment, mainly in the acute phase and to a lesser extent in the delayed phase. The most common points are Pericardium 6 (wrist) treated with conventional acupuncture needles, electro-acupuncture or acupressure. Auriculotherapy (ear acupuncture) has proven effective on nausea of pregnancy and postoperative nausea, but, to our knowledge, there are no studies published on the effect of auriculotherapy on CINV. These complementary treatments have virtually no side effects. In our institution, a simple treatment of acupuncture (2 points Pericardium 6 treated) and auriculotherapy (2 auricular point treated) is regularly use in patients who present CINV despite preventive treatment and most of them are relieved. The investigators propose a clinical trial in this population to assess symptoms improvement in patients presenting CINV after their first administration of chemotherapy despite adapted preventive treatment. Experimental treatment with semi-permanent needles takes place during administration of the second session of chemotherapy. CINV are evaluated through the (MAT) score that measures the frequency and intensity of nausea and vomiting in the 24 hours following the session and during the 4 days after administration Chemotherapy.
