Hypotension | Transcutaneous Electrical Acupoint Stimulation(TEAS) for Hypotension After Spinal Anesthesia in Parturients

Hypotension research study

What is the primary objective of this study?

The purpose of this study is to compare the effect of TEAS on hypotension after spinal anesthesia in patients undergoing cesarean section

Who is eligible to participate?

Inclusion Criteria: - Age>18yrs - American Society of Anesthesiologists(ASA) status 1-2 - Scheduled for elective cesarean under spinal anesthesia - Gestational age>38weeks, singleton pregnancy - Informed consented Exclusion Criteria: - Patients with pre-eclampsia or diabetes - Patients with hypertension or cardiac dysfunction - Disturbance of communication - Placental abruption

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?


Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Other:TEASElectric stimulation was given through electrode attached to specific acupoints

Other:Non-acupoint stimulationElectric stimulation was given through electrode attached to the shoulder

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

TEAS TreatmentPatients were given 30min of TEAS at PC6 after spinal anesthesia

Non-acupoint stimulationPatients were given 30min of electrical stimulation at shoulder after spinal anesthesia

ControlNo stimulation was given
