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.

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

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. KEYWORDS Intubation, Anaesthesia, Laryngoscopy |
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.
