Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression may occur with use of Fiorinal with Codeine.
Basic Analytical Toxicology Qualitative tests for poisons Many difficulties may be encountered when performing qualitative tests for poisons, especially if laboratory facilities are limited.
The poisons may include gases, such as carbon monoxide, drugs, solvents, pesticides, metal salts, corrosive liquids acids, alkalis and natural toxins. Some poisons may be pure chemicals and others complex natural products.
Not surprisingly, there is no comprehensive range of tests for all poisons in all samples. When certain compounds are suggested by the history or clinical findings, simple tests may be performed using the procedures given in the monographs section 6.
However, in the absence of clinical or other evidence to indicate the poison s involved, a defined series of tests a screen is needed.
It is usually advisable to perform this series of tests routinely, since circumstantial evidence of poisoning is often misleading. Similarly, the analysis should not end after the first positive result, since additional unsuspected compounds may be present. The sequence of analyses outlined in section 5.
The compounds detected include many that give rise to nonspecific features, such as drowsiness, coma or convulsions, and which will not be indicated by clinical examination alone. Poisons for which specific therapy is available, such as acetylsalicylic acid and paracetamol, are also included.
The analysis takes about 2 hours and may be modified to incorporate common local poisons if appropriate tests are available. Ideally, this liaison should commence before the specimens are collected, and any special sample requirements for particular analytes noted.
At the very least, a request form should be completed to accompany the specimens to the laboratory. An example of such a form is given in Fig. Before starting an analysis it is important to obtain as much information about the patient as possible medical, social and occupational history, treatment given, and the results of laboratory or other investigationsas discussed in sections 2 and 3.
It is also important to be aware of the time that elapsed between ingestion or exposure and the collection of samples, since this may influence the interpretation of results. All relevant information about a patient gathered in conversation with the clinician, nurse, or poisons information service should be recorded in the laboratory using the external request form Fig.
This is especially important if large numbers of patients have been involved in a particular incident, or a number of specimens have been obtained from one patient.
Confusion frequently arises when one or more blood samples are separated in a local laboratory and the original containers are discarded. The date and time of receipt of all specimens by the laboratory should be recorded and a unique identifying number assigned to each specimen see section 4.
Containers of volatile materials, such as organic solvents, should be packaged separately from biological specimens to avoid the possibility of cross-contamination. The presence of metabolites may sometimes assist identification if chromatographic techniques are used.
A ml specimen from an adult, collected in a sealed, sterile container, is sufficient for most purposes; no preservative should be added.
The sample should be obtained as soon as possible, ideally before any drug therapy is initiated. However, drugs such as tricyclic antidepressants amitriptyline, imipramine cause urinary retention, and thus a very early specimen may contain insignificant amounts of poison.

Conversely, little poison may remain in specimens taken many hours or days later, even though the patient may be very ill, as in acute paracetamol poisoning.
If the specimen is obtained by catheterization there is a possibility of contamination with lidocaine. If syrup of ipecacuanha has been given in an unsuccessful attempt to induce emesis there is a possibility of emetine being present in the urine.Introduction.
Different types of evidence may be presented to a forensic chemistry laboratory for analysis. This includes solid or liquid material such as powders, tablets, capsules, plant material or solutions and paraphernalia such as syringes, cookers, spoons, cigarettes and pipes.
Qualitative tests for poisons.
