Abstract
Objectives
To estimate, on the basis of anthropometric and demographic variables, the depth (Dp) and diameter (Dm) of femoral and jugular vessels, which have been located and measured by ultrasound, in pediatric patients.
Method
750 measurements of Dp and Dm of the femoral vein (FV), femoral artery (FA) and internal jugular vein (IJV) were made in 125 pediatric patients. The values were correlated with patients’ sex, weight, age, size and body surface area (BSA).
Results
Mean Dp values were 0.72 (0.34) cm for FA, 0.79 (0.35) cm for FV and 0.77 (0.24) cm for IJV. Mean antero-posterior Dm values were 0.37 (0.17) cm for FA, 0.42 (0.22) cm for FV and 0.59 (0.23) cm for IJV. In the studied pediatric patients, femoral and jugular vessels depth correlated with age, size, weight and BSA (R = 0.46–0.60); vascular depth could be estimated from patients’ weight and size (FA-Dp: R = 0.71; FV-Dp: R = 0.72; IJV-Dp: R = 0.53). Correlation with diameter was better for FA and FV (R = 0.81–0.89) than for IJV (R = 0.42–0.51); vascular diameter could be estimated from patient’s size (FA-Dm: R = 0.89; FV-Dm: R = 0.86; IJV-Dm: R = 0.52).
Conclusions
FV, FA and IJV depth and diameter correlated with weight, size, age and body surface area in the studied pediatric patients. Correlation was better for femoral than for jugular vessels. Depth could be estimated from patients’ weight and size, while diameter could be estimated from the size. Such estimations may facilitate the choice of vessels to be cannulated, length and diameter of cannulation needles and the diameter of catheters to be used in pediatric patients.
Sommario
Obiettivi
Calcolare in base a variabili antropometriche e demografiche, la profondita’ (P) e il diametro (D) dei vasi femorali e giugulari dei pazienti pediatrici in seguito alla loro localizzazione e misurazione ecografica.
Metodi
Sono state effettuatte 750 misurazioni della P e del D della vena femorale (VF), arteria femorale (AF) e della vena giugulare interna (VGI) in 125 pazienti pediatrici. I valori ottenuti sono stati relazionati con il sesso, il peso, l’eta’, l’altezza e la superficie corporea.
Risultati
La P media dell’ AF (PAF) è risultata di 0.72 (0.34) cm, quella della VF (PVF) di 0.79 (0.35) cm e quella della VGI (PVGI) di 0.77 (0.24) cm. Il D anteroposteriore medio dell’ AF (DAF) fu di 0.37 (0.17) cm, quello della VF (DVF) èrisultato di 0.42 (0.22) cm e quello della VGI (DVGI) di 0.59 (0.23) cm. Nei pazienti pediatrici analizzati, è stata riscontrata una relazione tra i parametri di eta’, peso, altezza e superficie corporea e quelli della profondita’ dei vasi femorali e giugulari (R = 0.46–0.60), che pùo essere stimata secondo peso e altezza (PAF: R = 0.71; PVF: R = 0.72; PVGI R = 0.53). La relazione con il diametro vascolare è risultata maggiore per l’ AF e la VF (R = 0.81–0.89) e piu’ bassa per la VGI (R = 0.42–0.51), che può essere stimata in base all’altezza del paziente (DAF: R = 0.89; DVF: R = 0.86; DVGI: R = 0.52).
Conclusioni
La profondita’ e il diametro della VF, dell’AF e della VGI si possono relazionare al peso, altezza, eta’ e superficie corporea nei pazienti pediatrici del nostro studio. Questa relazione e’ maggiore per i vasi femorali rispetto ai vasi giugulari, rendendo possibile il calcolo della loro profondita’ in base al peso e all’altezza e il calcolo del loro diametro vascolare in base all’altezza. Questi calcoli possono essere utili per la scelta adeguata del vaso da canalizzare, per la scelta del tipo e del calibro dell’ago e del catetere da usare nei pazienti pediatrici.
