Veress Needle Insufflation Technique: Tus Txheej Txheem Zoo Nkag Nkag Rau Laparoscopic Pneumoperitoneum

https://en.wikipedia.org/wiki/Veress_needle

1. Kev lag luam thiab kev kho mob cov ntsiab lus

Kev phais laparoscopic tso siab rau qhov ruaj khov pneumoperitoneum los tsim kom muaj qhov chaw ua haujlwm meej, thiabVeress koobinsufflation txheej txheem yog thawj txoj kev nkag rau hauv plab kab noj hniav. Clinically, qhov muag tsis pom trocar nkag mus thiab cov txheej txheem blunt puncture ib txwm tau nthuav tawm qhov tsis xws luag: kev tswj tsis tau qhov tob ua rau muaj kev sib tsoo visceral, tsis sib npaug ntawm cov roj txhaj ua rau asymmetric plab plab thiab qhov muag tsis pom kev phais, thiab kev nkag mus tsis tau yooj yim ua rau subcutaneous infusions thiab peritonema. Ntau tus kws phais me nyuam yaus tsuas yog tso siab rau qhov kev xav ntawm tactile kom ua tiav kev nkag, tsis muaj cov qauv kev txiav txim siab ntau, ua rau lub zog pneumoperitoneum tsis ruaj khov thiab lub sijhawm ua haujlwm ntev. Rau cov neeg mob rog rog nrog cov phab ntsa hauv plab thiab cov neeg mob rov ua haujlwm nrog lub plab adhesions, cov txheej txheem kev nkag tau muaj qhov ua tsis tau zoo heev, ua rau muaj kev pheej hmoo ntau ntxiv thiab muaj feem cuam tshuam tom qab phais. Kev lag luam tau ntev tsis muaj tus qauv tsim, rov ua dua thiab muaj kev nyab xeeb tag nrho lub plab nkag mus, ua tus qauv Veress koob insufflation txheej txheem yog ib qho tseem ceeb hauv kev txawj ntse rau niaj hnub minimally invasive phais.

2. Cov Ntsiab Cai Ua Haujlwm ntawm Veress Insufflation Technique

Lub hauv paus ntsiab lus tseem ceeb ntawm Veress koob insufflation nkag yog nyob rau hauv kev tiv thaiv kev tiv thaiv ua ke nrog kev siab -kev sib txawv pneumoperitoneum tsim, paub txog kev nyab xeeb kev sib tsoo thiab kev txhaj tshuaj ntau npaum li cas. Qhov sib txawv ntawm cov txheej txheem puncture zoo tib yam, cov txheej txheem no siv ob lub- txheej txheej nested qauv ntawm Veress koob los ua cov tshuab tsis siv neeg hloov pauv: lub sab nraud ntse cannula nkag mus rau cov txheej txheem plab phab ntsa hauv lub siab, thiab lub caij nplooj ntoos hlav sab hauv -loaded blunt stylet cia li tawm tom qab nkag mus rau hauv qhov qis - kab noj hniav kom tsis txhob muaj kab noj hniav. Lub caij no, tso siab rau cov qauv lumen ntawm lub cev koob, nws paub txog qis - ntws cov pa roj carbon dioxide txhaj tshuaj. Cov txheej txheem kev txiav txim siab tseem ceeb ntawm cov txheej txheem yog raws li nyob rau hauv intra- plab siab sib txawv: ib txwm intraperitoneal thawj lub siab yog stably qis dua 9 mmHg, uas tuaj yeem txheeb xyuas cov kab noj hniav nkag tau zoo thiab paub qhov txawv qhov tsis zoo xws li subcutaneous thiab preperitoneal insertion, fundamentally daws qhov mob ntawm misjud entry.

3. Kev faib tawm ntawm Veress Insufflation Cov khoom nkag

Raws li kev kho mob scenario adaptation thiab structural tsis, Veress koob nkag khoom txhawb insufflation txheej txheem yog cais los ntawm qhov loj thiab haumxeeb configuration. Cov qauv qauv tsim muaj qhov ntev ntawm 80-120 hli, sab nraud txoj kab uas hla ntawm 2.5-3 hli thiab cov roj lumen ntawm 1.5-2 hli, haum rau niaj hnub kev phais thiab gynecological laparoscopic nkag ntawm cov neeg laus laus. Extended enhanced qauv nrog 120-150 mm ntev thiab 3-5 mm txheej txoj kab uas hla yog customized rau cov neeg mob rog rog nrog tuab plab phab ntsa, zam kev nkag tsis txaus thiab koob lub cev slippage. Pediatric mini qauv txais 80 hli ultra- qauv luv thiab ultra- lumen zoo, sib piv cov me nyuam lub plab nyias phab ntsa thiab muag visceral anatomy kom txo tau cov nqaij ntshiv. Tsis tas li ntawd, lub siab- saib xyuas cov qauv sib xyaw ua ke yog nruab nrog tiag tiag- lub sijhawm ntsuas kev ntsuas lub sijhawm, txhawb nqa cov ntaub ntawv tawm tswv yim thaum lub sijhawm insufflation, uas tsim nyog rau siab -txoj kev phais qhov nyuaj.

4. Standard Veress Insufflation Entry Operational Guide

Tus txheej txheem Veress needle insufflation entry txheej txheem ua raws tag nrho - cov txheej txheem txheej txheem kom paub meej 100% kev nyab xeeb thiab ua tiav kev nkag. Kev tshuaj xyuas ua ntej -kev ua haujlwm: xyuas lub caij nplooj ntoos hlav rov ua kom yooj yim dua thiab lumen patency ntawm Veress koob, paub meej tias qhov tseeb ntawm cov khoom ntim tsis muaj menyuam thiab lub sijhawm siv tau ntawm cov khoom siv, thiab ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas. Kev npaj qhov chaw: xaiv qhov chaw ntawm qhov ncauj raws li qhov nyiam nkag mus, nqa lub plab phab ntsa vertically kom nce qhov kev ncua deb ntawm lub plab phab ntsa thiab viscera, thiab tshem tawm plab kab noj hniav. Puncture nkag: txais yuav qeeb tsis tu ncua -siab ntsug puncture, ntes ob pom tseeb tactile tawm tswv yim ntawm fascia thiab peritoneum breakthrough, nres nce mus sai sai tom qab xav tias tam sim ntawd tsis kam ploj. Cavity verification thiab insufflation: txuas lub raj insufflator, pib qis -flow roj txhaj hauv qab 1 L / min, paub meej tias thawj zaug intra- plab hnyuv siab<9 mmHg to verify correct intraperitoneal placement, then gradually increase flow rate, stably maintain intraoperative pressure at 12–15 mmHg, and complete symmetrical abdominal pneumoperitoneum establishment.

5. Kev paub txog kev kho mob thiab kev tiv thaiv kev pheej hmoo

Pem hauv ntej- kab kev kho mob tau sau tseg qhia tau hais tias kev nkag mus rau cov txheej txheem insufflation tuaj yeem txo qhov kev nkag mus rau - cuam tshuam txog ntau dua 90%. Ua ntej, tsis txhob nce lub koob txuas ntxiv tom qab kev tawg; ncua kev khiav hauj lwm rau 2-3 vib nas this kom paub meej tias lub caij nplooj ntoos hlav pib dua thiab blunt tip tiv thaiv ua kom, tsis txhob khawb visceral. Thib ob, nruj me ntsis ua raws li qis- ntws pib insufflation; siab - siab ceev cov roj txhaj tshuaj yooj yim ua rau preperitoneal gas tsub zuj zuj thiab visceral hloov chaw. Thib peb, rau cov neeg mob rov ua haujlwm nrog kev pheej hmoo adhesion, tso tseg qhov chaw nkag thiab xaiv cov ntsiab lus ntawm plab plab kom tsis txhob muaj adhesion plab hnyuv raug mob. Plaub, tom qab insufflating txog 1L carbon dioxide, me ntsis ua ntej koob 5 hli los tiv thaiv rab koob lub cev tawm los ntawm lub plab kab noj hniav nthuav. Thib tsib, txiav txim siab nkag mus siv tau los ntawm ntau qhov ntev nrog rau cov ntaub ntawv siab, lub plab symmetry thiab tactile tawm tswv yim, thiab tshem tawm ib qho kev txiav txim siab yuam kev.

6. Cov ntsiab lus thiab hauv - qhov tob sublimation

Veress koob insufflation nkag txheej txheem yog lub hauv paus ntawm standardized laparoscopic minimally invasive phais, realizing lub revolutionary upgrade ntawm plab nkag los ntawm dig muag empirical ua hauj lwm rau cov ntaub ntawv - coj ncaj kev khiav hauj lwm. Nws zoo kawg nkaus sib npaug ntawm kev nkag mus, cov ntaub so ntswg raug mob thiab kev nyab xeeb ntawm kev ua haujlwm, daws qhov ntev - sawv kev lag luam mob cov ntsiab lus ntawm kev pheej hmoo nkag siab thiab tsis zoo rov ua dua ntawm cov txheej txheem puncture. Cov khoom siv sib xyaw ua ke thiab cov qauv ua tiav tag nrho - txheej txheem kev ua haujlwm npog tag nrho cov pab pawg neeg mob thiab cov xwm txheej kev phais ib txwm ua, tsim kom muaj kev nyab xeeb nkag mus rau cov txheej txheem. Cov txheej txheem no tsis yog tsuas yog ib txoj kev phais yooj yim xwb, tab sis kuj yog lub cim tseem ceeb ntawm kev tsim kho thiab kho kom zoo ntawm kev phais me me niaj hnub no, muab kev ruaj ntseg ruaj khov rau txhua qhov kev ua haujlwm laparoscopic tom ntej.

7. Kev Txhim Kho Kev Lag Luam Kev Pom Zoo thiab Kev Pom Zoo Tshaj Tawm

Nrog rau kev txhim kho txuas ntxiv ntawm cov qauv kev kho mob me me, Veress insufflation nkag tshuab tau txhim kho mus rau kev txawj ntse, kom muaj nuj nqis thiab tag nrho -scenario adaptation. Nyob rau hauv lub neej yav tom ntej, kev txawj ntse siab- txuas Veress cov khoom nkag yuav paub txog cov kev tswj tsis siv neeg khiav thiab kev ceeb toom tsis zoo thaum ntxov, txo qis kev ua haujlwm yuam kev. Kev lag luam yuav tsim kev sib koom ua ke thoob ntiaj teb cov txheej txheem kev nkag mus rau kev tshem tawm kev ua haujlwm sib txawv los ntawm tus cwj pwm hauv cheeb tsam thiab tus kws phais neeg. Cov tsev kho mob yuav tsum ntxiv dag zog rau kev cob qhia tshwj xeeb ntawm cov txheej txheem nkag mus rau insufflation rau cov kws phais hluas, tsim cov xwm txheej- raws li kev ua haujlwm SOPs rau cov neeg mob tshwj xeeb. Cov khoom lag luam yuav tsum tau ua kom zoo dua rab koob lub cev ergonomics thiab lumen uniformity, txhim kho kev ruaj ntseg ntawm qis -flow insufflation, thiab tsis tu ncua polish kev nyab xeeb thiab raug ntawm Veress koob nkag tshuab kom muaj zog siab - kev txhim kho ntawm cov tshuaj tsawg tsawg.
