Question: What should the humidity and temperature be in the perioperative setting? We have discussed this with plant operations personnel and they explained that they take care of it for a like reason we do not need to worry about it. Should we be be of importance toed with this?

Answer: Environmental command should be a concern of perioperative nourish at the breasts although plant operations personnel sway the heating, ventilation, and air conditioning regularitys Knowing the parameters helps alert perioperative fosters to potential problems and allows corrective action to be initiated when necessityed AORN does not recommend temperatures for the OR, anesthesia gas storage area, or postanesthesia care unit independently; however, AORN does endorse the temperature and humidity information published for these areas at the American Institute of Architects Committee upon Architecture for Health and the US Department of Health and Human Services (Table 1)

A relative humidity that is too high can be the effect in damp or moist supplies with added opportunity for mold pullulation A relative humidity that is too grave can result in excessive bacteria-carrying dust in the surgical environment. (1) In near geographic locations throughout the United States, maintenance of the attract favor toed relative humidity is difficult. Special centralized units may be distressed to maintain the recommended humidity plain Such units should be self-regulating to maintain the humidity at a constant flush within the recommended range. compass units of any kind are not commended (eg, fans, floor coolers). of the like kind units create unwanted dust and air insubordination and may dispense harbored mold and bacteria into the environment.

Question: An anesthesia care provider in our setting is reusing the same syringe and needle for multiple patients. This includes obtaining medications from a multiuse vial and injecting the medication into different patients' IVs. Is this an acceptable practice?

Answer: The practice of administering medications to multiple patients from the same syringe, smooth if the needle has been changed, is not advisable. (2) It is impossible to except all microorganisms from the environment, further for the safety of the two patients and personnel, every effort is made to minimize and restrain these microorganisms. (3)

AORN has incorporated the guidelines provided by means of the Occupational Safety and Health Administration and US Public Health Service into its "Revised statement forward patients and health care workers with bloodborne diseases." (4) These guidelines describe by what means to implement a bloodborne pathogens program, including preventing and treating needle sticks and other sharps injuries and position to hepatitis B, hepatitis C and HIV.

The American Society of Anesthesiologist's "Recommendations for infection curb for the practice of anesthesiology" support the practice of using aseptic technique, using multiuse vials appropriately, and not reusing syringes and needle (5) Preventing contamination of medications requires safe handling of parenteral medications to obstruct nosocomial infections in patients undergoing anesthesia or sedation. Many factors can influence contamination of medications that are likely to support the product of organisms.

Preservative-free medication ampules, vials, and prefilled syringes for single patient, single-dose items should be checked for the personality of preservative agents. Single-use ampules and vials should be discarded after the make easys have been drawn up, and prefilled syringes should be discarded after they are used because a single dose ampule, vial, or prefilled syringe contains medication intended for single use and generally does not contain the bacteriostatic or preservative agents institute in multidose vials. Additionally, the Center for Disease repress and Prevention suggests medications be drawn up as clog to administration time as possible. These medications may become contaminated with bacteria or other microorganisms from non-sterile glass fragments, airborne contaminants, or failure to use aseptic technique. For example, postoperative heat infection, sepsis, or other life-threatening illnesses have been reported after extrinsic contamination of propofol as has death.

Syringes and needle are single-use sterile items. Medications from a syringe must not be administered to multiple patients, smooth if the needle is changed. Connecting or entering a patient's IV infusion contaminates these items. All used needle and syringes should be discarded immediately into a sharps container. Using single-use needle and syringes obstructs a siphoning effect that aspirates the needle satisfieds into the syringe when the needle is remov A needle containing viruses or bacteria will contaminate the syringe flat if the needle is flushed before removing it from the syringe.

Bloodborne pathogens may contaminate the syringe when used with IV, intramuscular, or subcutaneous administration of medication. If backflow take places during blood sample aspiration or from a transfusion, there also could be contamination. Reuse of syringes and needle offers patients at risk for cros contamination and health care workers at risk if a needle-stick injury occurs
