Help may not be forthcoming as each one is busy with his own job

In most of the nursing homes apart from the operating surgeon and anaesthesiologist the only staff is operating theatre nurse, ward boy and for major surgeries you may find a junior nurse to assist. Sometimes even this minimum staff may be missing and the help comes from the, sometimes surprisingly competent, sweeper of the nursing home. So it is presumed that you are alone and managing everything at your end. You may ask for various things and you are informed of their locations. After arranging your equipment you are supposed to put up a drape and place the scalp vein or needle. Over time you will become more familiar with the particular nursing home. A different nursing home will require you to start over again. You have to take the BP of the patient yourself, use your own tourniquet and set up a drip, taking into consideration the nature of the surgery and the position of the patient.
All the above can be learnt by accompanying a senior anaesthesiologist working in small nursing homes. Observe and ask any questions but do not try to help the anaesthesiologist (unless he asks for your help). This will train you to work single handed. Even in a major case the routine remains the same. You may request the surgeon to help (if needed) before he washes up for surgery.
