SAFETY OF USING DURAL PUNCTURE EPIDURAL ANALGESIA AS A METHOD OF LABOR ANALGESIA.

Objective: The aim: To evaluate the clinical characteristics of complications and side effects of CSE and DPE as a method of analgesia.

Patients And Methods: Materials and methods: The study included 137 patients who had a vaginal birth using one of two, CSE or DPE methods of analgesia. All of them were divided into two groups: Group I - 54 women (DPE group) and Group II - 83 women (CSE group). In group I, an epidural kit with a Tuohy G18 needle, G20 catheter, and a Whitacre G25 x 120 mm spinal needle was passed through the epidural needle for puncture of dura mater and removed after cerebrospinal fluid receiving, the epidural catheter was conducted on 3-4 cm. The initial dose of anesthetic was: 3 ml of Naropin 0.12% - test dose and 17 ml of working solution (Naropin 0.12% + Fentanyl 2 μg / ml) - main dose. In group II, a spinal-epidural kit with Tuohy G18 needle, catheter G20, spinal needle "Whitacre" G27 x 132 mm for dura mater puncture was used. Bupivacaine 1.5 mg + Fentanyl 15 mcg, 1 ml solution was administered spinally. To maintain analgesia in both groups - the patient-controlled analgesia with a working solution (Naropin 0.12% + Fentanyl 2 μg / ml) with a bolus of 8 - 10 ml, lockout 15 minutes.

Results: Results: The higher frequency of hypotension in childbirth when using CSE - 4 women (4.8%) vs 1 woman (1.9%) in the DPE group. Inadequate or insufficient analgesia in group I was found in 2 women (3.7%), and in group II in 4 women (4.8%). The severity of monolateral block in group I was not high and did not cause significant discomfort in women. The higher incidence of monolateral blockade was in group II, in three cases there was a need for additional anesthesiologist interventions and catheter manipulations. In the CSE group there were two cases (2.4%) of severe itching in women, in group I such an adverse reaction was absent. No complication such as PDPH was documented in either group.

Conclusion: Conclusions: 1. The use of the DPE technique showed a lower frequency of complications compared to CSE. 2. The use of a G 25 spinal needle for puncture of the dura mater does not lead to an increase in the frequency of PDPH. 3. DPE technique using G25 spinal needles reduces the need for additional manipulations with the epidural catheter to overcome unilateral blockades.
