ABSTRACT
Objective To explore the life experiences of donors undergoing pediatric living related liver transplantation and elucidate it 's the influencing factors of quality-of-life .Methods A qualitative study was performed with a phenomenological-hermeneutic approach .Twelve living related liver transplantation donors were face-to-face interviewed by a semi-structured interview and 7-step Colaizzi method was applied for data analysis .Results Four domains and 9 sub-domains were summarized as follows :body disturbance (pain ,discomfort & physical changes) ,sense of uncertainty (recipient-dependent sensitive ,self-doubt & confusion under family pressure ) ,role conflict (patient-carer & family-social) and contentment & gratitude (willing to sacrifice ,living in the present &benefiting from social funds ) .Conclusions The levels of quality-of-life vary greatly in different donors .Body disturbance ,sense of uncertainty ,role conflict ,contentment and gratitude are the major influencing factors of quality-of-life for donors undergoing pediatric living related transplantation .
ABSTRACT
[ABSTRACT]OBJECTIVETo assess the upper airway and related structures in different patterns of the upper airway obstruction on cine magnetic resonance (CMR) imaging in patients with obstructive sleep apnea hypopnea syndrome (OSAHS).METHODSCMR images of upper airway were obtained in 30 male patients with severe OSAHS during waking state and natural sleep. The midsagittal plane images were obtained. Patients were classified into 3 groups based on the upper airway obstruction patterns at apnea events and the reference data of the upper airway were measured.RESULTSDuring natural sleep, the diameter of retropalatal region, retroglossal region, retroepiglottic region and the length of suprahyoid muscles were significantly shorter than those during waking state (P<0.01). The maximum angle between the suprahyoid muscles and the apex of the tongue during natural sleep was significantly larger than that during waking state (P<0.01). During wakefulness, there was a significantly difference in the diameter of retropalatal region among 3 obstruction patterns (P<0.01). During natural sleep, there were statistical difference in the diameter of retropalatal region and the upper tongue, the angle between the hard palate and soft palate, the maximum angle between the suprahyoid muscles and the apex of the tongue, and their change values among 3 obstruction patterns (P<0.05). CONCLUSIONThe measurements of the upper airway and related structures on CMR imaging in OSAHS patients could provide useful information in assessing upper airway.
