Cov Tswv Yim rau Kev Xaiv Veress Needle Diameter Raws Li Tus Neeg Mob Lub Cev Habitus

Kev vam meej ntawm kev phais laparoscopic pib nrog kev ruaj ntseg ntawm pneumoperitoneum. Kev xaiv ntawm Veress koob txoj kab uas hla ncaj qha cuam tshuam qhov kev vam meej ntawm qhov pib puncture, qib ntawm kev mob tom qab, thiab qhov tshwm sim ntawm cov teeb meem. Clinically, cov kws phais yuav tsum yooj yim xaiv Veress koob ntawm qhov sib txawv ntawm qhov sib txawv raws li cov xwm txheej xws li tus neeg mob BMI, hnub nyoog, thiab keeb kwm ntawm kev phais plab ua ntej.

Standard Adults: Lub "Golden Zone" ntawm 3.5-4 mm Outer Diameter

Rau cov neeg laus nruab nrab nrog BMI ntawm 18.5 thiab 25, feem ntau cov kws phais neeg nyiam koob Veress nrog ib txoj kab uas hla ntawm 3.5-4 hli. Qhov loj me no muab qhov nruj txaus kom nkag mus rau qhov tsis zoo ntawm lub qhov quav thiab qhov peritoneum yam tsis tsim kom muaj qhov tsis xws luag ntawm lub plab loj heev. Cov kev tshawb fawb qhia tau hais tias thawj zaug - sim ua kom tiav nrog txoj kab uas hla no tshaj 95%, nrog rau qhov chaw nres nkoj tom qab- qhov chaw hernia tsawg dua 0.5%. Hais txog lub puab txoj kab uas hla, ib tug specification ntawm kwv yees li 2 hli kom ib tug nruab nrab insufflation ceev, tsis txhob diaphragmatic irritation los yog arrhythmias tshwm sim los ntawm overly ceev gas flow.

Cov neeg mob rog rog: Kev Sib Tw thiab Kev Tiv Thaiv - Vim li cas thiaj xav tau koob Thicker

Thaum BMI siab tshaj 30, lub subcutaneous rog txheej feem ntau tshaj 5 cm nyob rau hauv tuab. Nyob rau hauv tas li ntawd, ib tug zoo koob (OD <3 mm) yog heev raug rau buckling nyob rau hauv cov ntaub so ntswg adipose. Qhov no tuaj yeem ua rau "kev nkag tsis tseeb," qhov twg lub qhov taub nkag mus rau hauv lub peritoneum tab sis cov roj tau txhaj rau hauv qhov chaw ua ntej -peritoneal qhov chaw vim yog qhov deflection ntawm ncej, tsim cov pneumoperitoneum cuav uas cuam tshuam rau cov txheej txheem tom ntej. Yog li, rau cov neeg mob rog rog, hnyav - lub luag haujlwm Veress koob nrog OD ntawm 4-5 mm raug pom zoo. Cov koob no feem ntau yog tsim los ntawm 316L stainless hlau nrog nce phab ntsa tuab, ua kom lawv cov flexural modulus. Tsis tas li ntawd, qee cov qauv muaj kev tiv thaiv-slip texturing ntawm lub ncej kom yooj yim tuav thiab quab yuam thov. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txoj kab uas hla loj dua tsim qhov chaw loj dua; Yog li, fascial txheej yuav tsum raug kaw nrog absorbable sutures tom qab phais kom txo tau txoj kev pheej hmoo ntawm incisional hernia.

Pediatrics thiab Nyias Cov Neeg Laus: Refined Minimal Invasive Requirements

Cov neeg mob menyuam yaus muaj cov phab ntsa hauv plab nyias thiab cov viscera ilv, ua rau cov tshuaj 5 hli Veress koob ntau dhau. Pediatric -Cov koob tshwj xeeb Veress tau tsim nrog ib txoj kab uas hla sab nraud txo mus rau 2.5-3 hli thiab ib txoj kab uas hla sab hauv sib npaug rau 1.5-2 hli. Qhov "mini-needle" no muaj qhov tsawg kawg nkaus tiv thaiv, tso cai rau tus kws phais kom pom tseeb qhov kev tawg ntawm txhua txheej ntawm cov ntaub so ntswg los ntawm kev tawm tswv yim tactile. Txawm li cas los xij, vim lub lumen nqaim, lub sij hawm insufflation yuav txuas ntxiv los ntawm 20-30%, xav tau kev ua siab ntev. Lwm txoj hauv kev yog siv "optical Veress koob"- sib xyaw fiber ntau-optic bundle hauv stylet- tso cai rau tus kws phais kom pom cov koob taub hauv lub sijhawm. Qhov no ua rau kev siv cov kab me me (txog 2 hli) thaum ua kom muaj kev nyab xeeb.

Cov xwm txheej tshwj xeeb: Ntau qhov kev phais ua ntej thiab Adhesion Risk

Cov neeg mob uas muaj keeb kwm ntawm kev phais plab tuaj yeem ua rau lub plab tso rau ntawm phab ntsa plab. Qhov muag tsis pom kev hauv cov xwm txheej no muaj kev pheej hmoo siab, ua rau ntau tus kws phais neeg xaiv rau cov txheej txheem qhib (Hasson txheej txheem) es tsis txhob siv koob Veress. Txawm li cas los xij, yog tias yuav tsum tau siv rab koob Veress, ib rab koob nrog lub caij nplooj ntoos hlav blunt -loaded stylet (OD 5 mm) yog qhov nyiam, thiab lub kaum sab xis yuav tsum tau kho rau 45℃-60℃kom txo tau qhov tshwm sim ntawm kev raug mob ncaj qha rau lub plab. Notably, the stiffer, thicker shaft is less likely to deflect laterally when passing through dense adhesive tissue, helping to maintain a linear trajectory.

Xaus

Hauv cov ntsiab lus, kev xaiv ntawm Veress koob txoj kab uas hla yog tsis muaj qhov zoo li qub. Nws xav kom cov kws phais neeg soj ntsuam tus neeg mob qhov sib txawv ua ntej thiab kho kom zoo raws li kev tawm tswv yim tactile thiab cov lus teb intraoperative. Xaiv cov koob tsim nyog feem ntau ua rau muaj kev phom sij tshaj plaws "thawj kauj ruam" ntawm kev phais ib txoj kev tswj thiab tswj tau.
