METABOLISME DARAH SELAMA PENYIMPANAN

Pada darah yang disimpan di luar tubuh (dalam botol/kantong plastik), dimana kondisinya sangat berbeda dengan kondisi dalam tubuh, dan keseimbangan alamiah tidak ada, maka tentunya akan terjadi perubahan-perubahan dalam berbagai hal, termasuk perubahan-perubahan dalam metabolisme darah tersebut.

Adapun perubahan-perubahan yang terjadi selama penyimpanan invitro tersebut adalah sebagai berikut :

1. Daya hidup sel darah merah

a. Daya hidup sel darah merah

Pada waktu penyadapan dalam botol ± 1 – 5 % sel darah merah rusak.

Setelah darah disimpan 2 minggu dalam ACD, walaupun hampir semua sel darah mudah hidup normal setelah ditransfusikan, kira-kira 10 % musnah dalam waktu 24 jam. Setelah penyimpanan 4 minggu dalam ACD, daya hidup setelah transfusi menurun dan sebanyak 25% dari sel darah merah hancur dalam bekerja jam pertama setelah transfusi. Makin lama darah disimpan makin banyak sel darah merah yang dihancurkan dan makin kecil jumlah sel darah merah yang dapat bertahan hidup. % sel darah merah yang hidup 24 jam setelah transfusi menjadi patokan perhitungan masa simpan darah dalam bentuk cair, minimal 70 %. Bila sel darah merah yang hidup 24 jam setelah transfusi <>® tidak baik untuk resipien.

Terapi Oksigen

Pengertian dan definisi terapi oksigen
Terapi oksigen adalah pengelolaan oksigen tambahan pada pasien untuk mencegah atau menangani hipoksia. Hipoksia adalah satu kondisi dimana tidak terpenuhi oksigen untuk memenuhi kebutuhan metabolisme jaringan dan sel (Herry and Potter, 2006).

ABSTRACT
Airway assessment is the most important aspect of anaesthetic practice as a difficult intubation may be unanticipated. A prospective study was done to compare the efficacy of airway parameters to predict difficult intubation. Parameters studied were degree of head extension, thyromental distance, inter incisor gap, grading of prognathism, obesity and modified mallampati classification. 600 Patients with ASA I& ASA II grade were enrolled in the study. All patients were preoperatively assessed for airway parameters. Intra-operatively all patients were classified according to Cormack and Lehane laryngoscopic view. Clinical data of each test was collected, tabulated and analyzed to obtain the sensitivity, specificity, positive predictive value & negative predictive value. Results obtained showed an incidence of difficult intubation of 3.3 % of patients. Head and neck movements had the highest sensitivity (86.36%); high arched palate had the highest specificity (99.38%). Head and neck movements strongly correlated for patients with difficult intubation.

Introduction
The fundamental responsibility of an anesthesiologist is to maintain adequate gas exchange through a patent airway. Failure to maintain a patent airway for more than a few minutes results in brain damage or death1. Anaesthesia in a patient with a difficult airway can lead to both direct airway trauma and morbidity from hypoxia and hypercarbia. Direct airway trauma occurs because the management of the difficult airway often involves the application of more physical force to the patient’s airway than is normally used. Much of the morbidity specifically attributable to managing a difficult airway comes from an interruption of gas exchange (hypoxia and hypercapnia), which may then cause brain damage and cardiovascular activation or depression2.
Though endotracheal intubation is a routine procedure for all anesthesiologists, occasions may arise when even an experienced anesthesiologist might have great difficulty in the technique of intubation for successful control of the airway. As difficult intubation occurs infrequently and is not easy to define, research has been directed at predicting difficult laryngoscopy, i.e. when is not possible to visualize any portion of the vocal cords after multiple attempts at conventional laryngoscopy. It is argued that if difficult laryngoscopy has been predicted and intubation is essential, skilled assistance and specialist equipment should be provided. Although the incidence of difficult or failed tracheal intubation is comparatively low, unexpected difficulties and poorly managed situations may result in a life threatening condition or even death3.
Difficulty in intubation is usually associated with difficulty in exposing the glottis by direct laryngoscopy. This involves a series of manoeuvres, including extending the head, opening the mouth, displacing and compressing the tongue into the submandibular space and lifting the mandible forward. The ease or difficulty in performing each of these manoeuvres can be assessed by one or more parameters4.
Extension of the head at the atlanto-occipital joint can be assessed by simply looking at the movements of the head, measuring the sternomental distance, or by using devices to measure the angle5. Mouth opening can be assessed by measuring the distance between upper and lower incisors with the mouth fully open. The ease of lifting the mandible can be assessed by comparing the relative position of the lower incisors in comparison with the upper incisors after forward protrusion of the mandible6. The measurement of the mento-hyoid distance and thyromental distance provide a rough estimate of the submandibular space7. The ability of the patient to move the lower incisor in front of the upper incisor tells us about jaw movement. The classification provided by Mallampati et al8 and later modified by Samsoon and Young9 helps to assess the size of tongue relative to the oropharynx. Abnormalities in one or more of these parameters may help predict difficulty in direct laryngoscopy1.
Initial studies attempted to compare individual parameters to predict difficult intubation with mixed results8,9. Later studies have attempted to create a scoring system3,10 or a complex mathematical model11,12. This study is an attempt to verify which of these factors are significantly associated with difficult exposure of glottis and to rank them according to the strength of association.
