Txoj Kev Xaiv Cov Ntiv Nplhaib Qhov Loj hauv Obstetric Anesthesia

Obstetric anesthesia yog arguably ib qho nyuaj tshaj plaws arenas rau daim ntawv thov ntawm tus txha caj qaum. Cov kev hloov pauv ntawm lub cev hauv cov neeg mob cev xeeb tub, kev xav txog kev nyab xeeb ntawm fetus, thiab qhov tshwj xeeb xav tau ntawm kev ua haujlwm analgesia hloov kev xaiv ntawm tus txha caj qaum loj rau hauv daim duab zoo nkauj.

I. Qhov txawv ntawm Tus Neeg Mob Obstetric

Tus txha caj qaum anatomy ntawm tus poj niam cev xeeb tub muaj kev hloov pauv loj. Lub tsev menyuam loj exacerbateslordosis ntawm lumbar, thiab nce intra- plab siab ua rau congestion thiab dilation ntawmepidural venous plexus, nce qhov kev pheej hmoo ntawm los ntshav thaum puncture. Tseem ceeb tshaj, tus niamdural nro yog siab dua, uas sib txuas ua rau muaj kev pheej hmoo ntawm CSF leakage post-puncture. Cov poj niam tom qab yug me nyuam lawv tus kheej yog ib pab pawg muaj kev pheej hmoo siab rauNcej -Dural Puncture Headache (PDPH), nrog qhov xwm txheej2 mus rau 3 npaug siab dua​ tshaj lawv cov uas tsis yog - cev xeeb tub.

II. Spinal Anesthesia: Thick vs. Nyias Trade-tawm

HauvCesarean Section (C-section), spinal anesthesia yog ib qho ntawm cov kev siv tshuaj loog tshaj plaws. Kev lig kev cai, obstetricians nyiam25g lossis 26gtus txha caj qaum. Qhov kev xaiv no sib npaug txaus txhaj tshuaj ceev rau cov tshuaj loog hauv zos nrog rau qhov txaus ntshai PDPH (kwv yees3%–5%).

Nyob rau hauv xyoo tas los no, lub27G cwj mem -point koobtau pom ntau zuj zus siv nyob rau hauv obstetrics. Cov kev tshawb fawb pom tau tias siv 27G koob tuaj yeem txo tus niam PDPH tus nqi rau< 1%. Txawm li cas los xij, qhov tsis zoo ntawm cov koob zoo yog qhovtseem ceeb nce nyob rau hauv kev txhaj tshuaj tiv thaiv. Hauv qhov xwm txheej ceev C-section, txhua thib ob suav. Yog tias muaj kev tiv thaiv siab qeeb kev tswj hwm tshuaj, nws yuav ncua sijhawm sijhawm phais. Yog li ntawd, qee tus kws kho mob tshuaj loog, thaum ua tiav kev sib tsoo, xaiv los txhaj me me ntawm huab cua lossis ntsev los ntawm rab koob zoo kom paub meej tias qhov kev tso kawm zoo ua ntej hloov cov koob txhaj tshuaj, yog li txhim kho kev ua haujlwm.

III. Labor Analgesia: Combined Spinal-Epidural (CSE)

Hauv kev ua haujlwm analgesia, tusCombined Spinal -Epidural (CSE)Cov txheej txheem sib koom ua ke qhov pib sai ntawm cov leeg txha caj qaum nrog kev txhawb nqa kev muaj peev xwm ntawm epidural analgesia. Cov txheej txheem no yuav tsum muaj antev, zoo txha caj qaum koob(feem ntau25G–27G, ntev ~ 120 mm) kom dhau los ntawm lumen ntawm koob epidural mus rau qhov chaw subarachnoid.

Qhov luaj li cas ntawm no yog tshwj xeeb nuanced. tuab heev (< 25G) increases PDPH risk; too thin (>27G) tuaj yeem cuam tshuam CSF rov qab los, ua rau nws nyuaj rau kev lees paub qhov tseeb qhov kev tso kawm ntawm rab koob. Tsis tas li ntawd, rab koob yuav tsum ntev txaus kom protrude kwv yees1 cm ibdhau los ntawm qhov kawg ntawm rab koob epidural, tseem tsis tau ntev npaum li ua rau muaj kev pheej hmoo ua rau puas tsuajmob medullaris. Li no, mob siab rau CSE spinal koob yog feem ntau standardized ntawm120 hlinyob rau hauv ntev kom haum rau qhov tob ntawm lub epidural koob.

IV. Cov Ntsiab Cai ntawm Kev Xaiv Tus Kheej

Tsis muaj ib qhov loj me haum rau tag nrho cov hnub nyoog. Anesthesiologists yuav tsum ntsuas cov hauv qab no kom meej:

• Lub cev Mass Index (BMI):Obese parturients xav tau koob ntev (feem ntau5 nti / 127 mm).
• Tus txha caj qaum Anatomy:Nyob rau hauv cov neeg mob uas nqaim intervertebral qhov chaw, cov koob zoo yog yooj yim rau buckling; ib rab koob me ntsis tuab yuav tsim nyog.
• Kev paub ntawm tus neeg ua haujlwm:Cov kws kho mob novice muaj qhov ua tiav qis dua nrog 27G koob thiab yuav pib nrog 25G.
• Ceev ceev:​ Thaum muaj xwm txheej ceev C-section, qhov ntsuas yuav tau so24Gkom ntseeg tau tias kev xa tshuaj sai sai.

Xaus

Nyob rau hauv obstetric tshuaj loog, xaiv ib tug spinal koob loj yog ib tug meej ntsuas ntsuas. Nws yuav tsum tiv thaiv kev nyab xeeb ntawm leej niam thiab menyuam thaum sib npaug ntawm cov txheej txheem ua tau zoo thiab sijhawm sijhawm. Lub koob me me no dais qhov hnyav ntawmob lub neej, thiab txhua qhov kev xaiv muaj lub luag haujlwm tseem ceeb.
