upper airway. (2008) In the Perioperative setting, patients with
diagnosed or suspected OSA are managed closely due to a po-
tential for complications. The American Society of Anesthesia
(ASA) and the American Society of Perianesthesia Nurses
(ASPAN) have adopted guidelines for the care of the OSA
patient. This institution is in the process of developing guide-
lines for the OSA population.
The purpose of this research was to answer the following
questions: What is the Phase I length of stay for the known
OSA patient with or without a Bipap machine? Were there
any adverse respiratory events in the first 3 post-operative
days?
This descriptive quantative study focuses on 50 randomized
diagnosed OSA patients at a community hospital. The inclu-
sion criteria were: patients with a diagnosis of OSA undergo-
ing surgery and requiring admission. Data was obtained
through current/concurrent chart review. Patients were fol-
lowed for three days postoperatively with a follow up phone
call made one week post discharge. Fourteen patients of the
50 patients had identifiable respiratory events in Phase I peri-
anesthesia unit (PACU). Their oxygen saturations ranged
from 77%-88% on arrival in PACU. To correct hypoxia, nine
required Continuous Positive Airway Pressure (CPAP) and
five required airway maneuvers. For these patients, length
of stay in the PACU was 1-7 hours. Thirteen of the event pa-
tients received general anesthesia. No apnec events were
recorded for any of the patients on 3 consecutive post oper-
ative days. Only 25 patients were able to be reached for the
postoperative phone call. The patients who did not have
CPAP machines, reported nightmares, trouble sleeping and
daytime sleepiness. Only 3 patients used their CPAP when
napping during the day.
Findings of this study maybe used in the development of institu-
tional specific guidelines. OSA patients requiring general anes-
thesia require closer peri-operative monitoring to ensure
adequate respiratory function. A multidisciplinary approach is
needed for the safety of the OSA patient. Nursing staff must
be vigilant for patient complications. Nursing and respiratory
therapy need to encourage patient compliance with CPAP
equipment.

USING PICTURE COMMUNICATION TO ASSESSPAIN LOCATION IN CHILDRENPrimary Investigator: Phyllis J. Mesko, RN, CPN
Akron Children’s Hospital, Akron, Ohio
Co-Investigator: Aris Eliades, PhD, RN, CNS
Introduction/Problem: This study expands on findings sup-
porting that picture communication tools effectively assess
pain location.
Purpose: The study seeks to determine effectiveness of a pic-
ture communication aid, the Mesko-Eliades Pain Area Locator
(PAL) tool, and parent satisfaction with the use of the PAL
among post-anesthesia pediatric patients (ages 3 to 9 years) un-
dergoing a broad range of same-day surgical procedures.
Methodology: Employing a quantitative, comparative design, a
convenience sample of post-operative patients undergoing
same day surgeries was recruited at a freestanding, Magnet
designated pediatric hospital. Post-operative pain location
assessment was performed in the PACU by two individuals: 1)
a PACU nurse completed standard pain assessment; 2) a non-
PACU data collector performed a second pain location assess-
ment with the PAL. Parent Satisfaction was measured through
completion of a ten item satisfaction survey.
Results: To determine consistency between the pain assessment
by the nurse and data collector (using the PAL to determine pain
location), the proportion of agreement, ranging from 0 to 1, was
calculated for41participants. Themeanproportionof agreement
was 0.24 (SD 5 0.435) which is significantly lower than 1, t 5-11.136, p 5 .000. Parent survey responses exceeded historical
data. For the item “Nurses concern for comfort”, the response
of 100% was higher compared to historical data (m 5 93.3%).
For the item “Degree pain was controlled”, the mean response
of 97.3% was higher compared to historical data (m5 93%).
Discussion/Conclusion: Post-anesthesia pediatric patients
undergoing a broad range of same-day surgical procedures
effectively used the PAL to identify location of pain. There
was an inconsistency between the nurse’s assessment of pain
location and the pain location identified by the child using
the PAL. Parents were highly satisfied with the PAL.
Implications for Perianesthesia Nurses and Future
Research: Perianesthesia clinical practice standards are
advanced by the findings that patients undergoing a variety of
pediatric surgical procedures effectively used the PAL post-oper-
atively to identify location of pain and parent satisfaction with
the PAL increased compared to standard pain location assess-
ment. Studies establishing reliability and validity and random-
ized intervention studies on the use of the PAL are indicated.
PERI-OPERATIVE HYPOTHERMIA: ACTIVE VSPASSIVE WARMINGPrimary Investigators: Jenise Rice, MSN, RN, CPAN
UT MD Anderson Cancer Center, Houston, Texas
Co-Investigators: Karen Salinas, BSN, RN, CPAN, Kate
Mask, MSN, RN, CPAN, Elsy Puthenparampil, MSN, RN-BC, CPAN
Identification of the problem: Peri-operative hypothermia
has been associated with a range of adverse effects. During a
ASPAN NATIONAL CONFERENCE ABSTRACTS e41
random chart audit, an inconsistency was discovered in moni-
toring temperatures within 15 minutes of the patient’s arrival
to the Post Anesthesia Care Unit (PACU) per ASPAN standards.
Many newly hired staff were not aware of this standard and
its importance as it relates to the treatment of hypothermia.
This caused a problem in timely recognition and management
of hypothermia in patients admitted to PACU. In order to
achieve the best outcomes for patients with hypothermia, a
literature search was performed to determine the best method
of warming.
EP Question/ Purpose: The EBP team reviewed the literature
for best evidence on the most effective method to maintain
normothermia in adult PACU patients: active or passive
warming?
Methods/ Evidence: A systematic literature review was con-
ducted using key words: perioperative warming, perioperative
hypothermia, perioperative normothermia in electronic data-
bases including PubMed, SCOPUS, CINAHL, Cochrane and
Ovid. The search was limited to Humans, Adult patients, and
English. Thirteen articles were selected.
Significance of Findings/Outcomes: Maintaining normo-
thermia throughout the perioperative environment reduces
the total costs for anesthetic treatment through lower incidence
of mechanical ventilation, reduced intraoperative blood loss,
and shorter PACU stays. Active warming with circulating water
garments and forced-air warming were more effective at
maintaining perioperative normothermia and preventing post--
operative hypothermia compared to passive warming interven-
tions. Circulating water garments were found to be more
effective in active warming than forced-air warming. A unit
wide education using PowerPoint presentation and team
huddles preceded the implementation of the Clinical Practice
Guideline. Clinical leaders in the unit function as resource in
supporting and monitoring the new practice.
Implication for peri-anesthesia and future research: Evi-
dence supports the implementation of Clinical Practice
Guideline to standardize monitoring and management of hypo-
thermia in PACU and the use of forced-air warming to improve
patient outcomes that include decreased rates of surgical site
infection, increased thermal comfort and decreased PACU stay.
Further research on the advantage of active warming with circu-
lating water garments compared to forced air warming is recom-
mended.
EFFECT OF AN INDIVIDUALIZED INSTRUCTIONFORM ON PATIENT KNOWLEDGE OFPERIOPERATIVE ANTICOAGULANT AND/ORANTIPLATELET MEDICATION MANAGEMENTPrimary Investigators: Carolyn Scratchard, RN, MSN-NSA,

Introduction:Management of perioperative patients who take
anticoagulant/antiplatelet medications is an important patient
safety issue. The U.S. Joint Commission (2013) identified the
need to decrease patient injury associated with the use of anti-
coagulant therapy as a Hospital National Patient Safety Goal and
suggested practice change. One such practice change is the for-
mation of medication management plans specific to the use of
anticoagulant/antiplatelet medications. It was further sug-
gested that these management plans be a multi-disciplinary
approach (Thachil, 2008).
Problem: While conducting pre-health assessments preadmis-
sion nurses discovered that some patients who take anticoagu-
lant/antiplatelet medications do not understand how tomanage
these medications perioperatively.
Purpose: Evaluation of whether or not same day surgical pa-
tients who take prescribed anticoagulant/antiplatelet medica-
tion and receive individualized education have increased
knowledge on how to manage these medications periopera-
tively compared to patients who received standard care.
Methodology: This randomized clinical trial interviewed sixty
adult patients scheduled for same day surgery who take pre-
scribed anticoagulant/antiplatelet medication. Randomly
distributed into two groups, patients were either given an indi-
vidualized instruction form or did not receive individualized in-
struction and were assessed using the standard interview
practice of the surgical center. Patient knowledge was assessed
by asking both groups identical questions. Data was analyzed
using chi-square to determine p values.
Results: This study demonstrated a significant improvement in
knowledge regarding anticoagulant/antiplatelet medications
among patients who received individualized education. One
hundred percent of the patients receiving this education under-
stood their medication usage compared to 50% who knew
when to stop (, .01) and 7% who knew when to restart
(, .01) following surgery.
Discussion: The multi-disciplinary approach utilized focuses
on promoting high quality patient-centered care and promotes
maximum patient safety throughout the perioperative process.
Conclusion: The use of an individualized instruction form
involving collaboration of the surgeon and the physician pre-
scribing the anticoagulant/antiplatelet medication showed an
increase in patient knowledge on how to manage these medica-
tions perioperatively.
Implications: This improved communication and increased
patient knowledge about anticoagulant/antiplatelet medication
has the potential to decrease unintentional adverse events.

Introduction: The American Pain Society created a policy
statement in 1995 coining the phrase “pain-the fifth vital
sign”. Since 2000, there have been guidelines published that
emphasize the need for improved identification and manage-
ment of pain in children.
Identification of the problem: Despite the advancements in
the assessment and management of pediatric pain, it is esti-
mated that pediatric patients are under medicated for pain
relief.
