An audit of failed instrumental deliveries was undertaken to assess the incidence of complications and the adequacy of documentation. When one instrument has failed to effect delivery, the use of a second instrument could in most cases be used to complete the delivery without harm to the mother or baby. However in a small but significant number of cases there are severe maternal or perinatal complications, and these could be the subject of litigation. This could be avoided by adequate pre-application assessment, standard conduct of instrumental delivery and full documentation. Inadequate documentation could be overcome by the use of a pro forma. Selective use of plastic and metal cups could reduce the incidence of failed attempts.

Methods of Sterilization II: Chemical Methods

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Assessment of apical pulse

Assessing the Apical Pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
Assessment of apical radial pulse01:25

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Special considerations while measuring pulse

Assessing a patient's pulse is a fundamental skill in healthcare, but certain situations require special attention:
Assessing Blood pressure using a doppler ultrasound01:19

Assessing Blood pressure using a doppler ultrasound

To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.
