Graduation 11 March B.E. 2539 ( 1996 ), M.Ed. , Ed.D. ) ABSTRACT Critically ill children especially those who need mechanical ventilatory support are most sensitive to the change of oxygenation. To determine whether common nursing cares in the PICU could effect the oxygen status of this vulnerable group of patients, a descriptive research was conducted concerning 4 activities ; weighing , suctioning , bed bath and lV access or blood drawing. Patients' baseline parameters oxygenation I , muscle relaxant and or sedative drug and the duration ; age , patient's of each activity that could predict the change in oxygenation were also evaluated, Patients were classified into 3 groups by using their oxygenation ( PaO2lFiO, ) prior the time activity were done to grade the severities ; normal oxygenation , moderate abnormal oxygenation and severe abnormal oxygenation. Serial arterial orygen saturation ( SpO, ) measured by pulse oximetry ( Nellcor@ N - 200 ; Hayward , California )were manually rEcorded every 15 sec. while those 4 activities were routinely performing in the PICU, Ramathibodi Hospital during December 1, 1994 March 31 lt , 1995. Among 174 observations , we found that all activities did cause reduction in SpOr. The patients with sEvere abnormal oxygenation as classified by PaO, ton I Vo demonstrated I FiOrl 2gg the maximum reduction in SpOr, Weighing and suctioning caused -_: -_..--/ il r! maximum reduction in SpO, ( mean SpO, reduction = 14.52 * Z.gS %o and 14.26+7.29 respectively ). Regression analysis revealed that patients' baseline oxygenation ( PaO, / olo FiO2 ) and the duration of activities performed until SpO, fell to the lowest level could predict the severity of desaturation occurring in all activities. Age was an additional important factor predicting the degree of desaturation caused by weighing; the younger the patient, the lower the SpOr, t These data suggest that common nursing cares in the PICU all can cause desaturation in mechanical ventilated children. Appropriate nursing techniques and equipment particularly for weighing and suctioning should be emphasized of desaturation. f, 0 to prevent detrimental effect t meriru v lru'l | 69av il?venry0q8r fifinreuilevnrrt rl . uuA'ordanrmlile n-fl undorcianrmd'snqu Fl-.3 nTr:irp q-o nm:irgnrer.r {-{ nrairgnrvr jo :.lvtvt ' 1 ilytu1 I nrcrrurfluillLLnvnolrdrd'rpto.rrlrpur 1 drnrLr6{a 6 neouuuahpufi.rvrq:*fi 7 inq:jermnftra.rnrei{s 17 nuqfigruna{nrai{Er 't8 gou t TN rJ t?r ngo.r nT 16"A ?v mfl uvr ?t o Fr v r ayrri{et or.i rq 20 vtfii:r 21 ev l0qlnFWo.tnleeqEl 22 fietrrufreu:la 22 'tt urd z orr*nrrrudrdse{o.r 25 ida64 nellJorJ ne:romonQ rqu'luuno nm:Jfr rlfi fi u nmudd.,fl or ulunreq rdaor un.r unvfls{sfi fi 6vr6na ua {rJca rfi 25 ndtd rnrdosdceurnlq 31 uavrJnn?vvruga.rfi qneeuoioevdunr':ril6ild'esro.iaonS tquluuaa . r} nmrufri.tfiud'evra,ir.rorq flu ncrrudr.r d'eto.roo nB tqu'[uuno fl r n ar€.r n frr u rdu u^ r,jveo4 ru. av{u:l avnr n ua vn c r u nr n'rruoilriesro{oan? lsuluunomrnon un.r o 6o n t6o o uors frrufiuf,esu,j't{sr rTu or unt 46 48 t dlrrTsu ( sia ) urir nrnjavfiunrcvoonfitqu nra'ilrvfi unmsndotoo d n? rqulnetfrfi'ndao nfi fi rnai av a -€cJc 50 63 :.lvrvt 3 efi'n1tuun1?eqfl I finsruv:lavfl 1n? d 4 4Jocal un v nrerdo n nrj u d"Joeir.i a' rn?a{ilovrtfl tunlfesEl 1flr1 n q 65 n1?rfi:neuaeru{aqn 65 €t, nlmmflvusailn u"d + ilnnrat{fl 67 unvnreimrnvr,f{oryn e& ururfi ug1ffi d'n nn1?vt Ft6ounr.nl figT 7A 70 a.i n 4 il d'e o Ej''r.$ arnnmu:ldsuu:la.r rirrrerru6u d'cso.roon? tqu'[uunoor tdarr uot.l zu 63 64 I d at fuJl 11Ifl O.i tFt?O{ il A C q EJ 6 54 uro{ nrei{fl nrrafi:lvrsrJn 74 83 91 ? urd s aq:Jarnnrei{s unv {ar{uouuv nq:Jrunnrfi6e fro mua 108 uuvlun ref r ru ai v 108 c ev a 1A t6UA UUy tiln','l?n1Cqfl {et:ltfr Y , u 109 r nf{ no u.J u??ru1qnfl.r 111 113 nlnt{u')n nlnt{uen t i a loorr ^v tunltcsfl n.
