METHOD OF ANALGESIC DELIVERY Russian patent published in 2020 - IPC A61M19/00 A61K31/167 A61P15/04 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to obstetrics-gynaecology and anaesthesiology, and can be used for labour pain anaesthesia. That is ensured by epidural analgesia with local anaesthetic introduction. Local anaesthetic is represented by levobupivacaine in concentration of 0.075 %. In the presence of regular labour, a puncture and catheterisation of the epidural space is performed at the level of L3-L4/L4-L5, a test dose of the solution of lidocaine hydrochloride 2 % - 3.0 is introduced. After 5 minutes, an anaesthetic is induced by administering levobupivacaine 0.075 % - 10.0 ml. In 15 minutes with insufficient anaesthesia, the VAS score >40 mm additionally involves levobupivacaine 0.075% - 10.0 ml. If an analgesic effect is achieved, the infusion pump Mini Rythmic Evolution Micrel Medical Devices SA is connected in 30 minutes with a program of intermittent administration of epidural boluses of levobupivacaine 6.0 ml every 30 minutes in a combination with patient-controlled epidural analgesia in bolus anaesthetic - 6.0 ml, lockout interval - 30 minutes. Programmed intermittent epidural boluses are introduced in the first and second delivery periods, the introduction is stopped after the delivery.

EFFECT: method provides pronounced analgesic effect in the absence of development of the motor block, negative effect on the dynamics of labour, foetus and newborn's condition, reduced cases of breakthrough pain, increased satisfaction of women in labour with the analgesia, reduced frequency of instrumental delivery due to prevention of motor unit development.
